Introduction to RIPE NCC
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 4
What is the RIPE NCC?
• Network Co-ordination Centre– The RIPE NCC is a “co-ordination” and support service for
its members and RIPE community
• One of 3 Regional Internet Registries (RIR)
• Why a NCC ?
Actions agreed in RIPE community needed– continuity and professionalism– neutrality and impartiality
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 5
Vital Statistics• Statistics 1992
– 3 staff members– No Local IR’s– 182,528 hosts in European Internet– 7,955 objects in RIPE database (June ‘92)
• Statistics Now– 62 staff (22 nationalities) 2,018+ participating Local IR’s 11,390,000+ countable hosts in the RIPE NCC region 3,041,650+ objects in the database
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 6
RIPE NCC Activities (1)
• Registration Services– IPv4 addresses
– IPv6 addresses
– AS numbers
– LIR Training Courses• <[email protected]>
• Reverse domain name delegation– NOT registering domain names

Communication with <[email protected]>
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 35
Ticketing System
• Unique ticket number– facilitates retrieval / archiving– NCC#YYYYMMXXXX e.g. NCC#2000053280
• Check status of ticket on the web– http://www.ripe.net/cgi-bin/rttquery
• open ncc • open reg• closed
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 36
Hostmaster-robot• Checks request form
– Reg-ID, contact persons– syntax– policy problems
• Acknowledgement & diagnostics– LONGACK
• Error message– correct & re-send the request– use same ticket number– NOAUTO
• No errors: hostmaster wait-queue– “ongoings” directly to hostmasters
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 37
Request Approved
• With the first ASSIGNMENT approved LIR automatically gets an ALLOCATION– /20 (4096 addresses)
Hostmaster enters allocation and assignment objects into the RIPE database at this time- /24 & /25 & /26 instead of /23
• Whole allocated range can be announced immediately
• Every request has to be sent for approval to RIPE NCC – addresses for LIRs own infrastructure
– all customers’ request

• All the data communicated with RIPE NCC is kept strictly confidential
• Documentation for RIPE NCC has to be in English
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 43
Evaluation -- General Information
• #[Overview of organisation template]#• information relevant to the address space request
– Name and location of the company?– What are the company activities?– What is the structure?
• Does it have subsidiaries and where?• For what part of the company are the addresses requested?
• #[Requester Template]#– LIR contact for RIPE NCC
• #[User Template]#– customer’s contact for LIR
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 44
Evaluation -- Addressing Plan• Do totals in “Addressing Plan” match numbers in
“Request Overview”?
• Are all subnets classless?– are the subnet masks real?
• Utilisation and efficiency guidelines: 25% immediately, 50% in one year
• Can address space be conserved by using– different subnet sizes?– avoiding padding between subnets?
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 45
Evaluation -- Network Template• inetnum value
– specifies the size of assignment– actual range is not necessary
• Relevant netname– descriptive; uppercase letters, numbers & “-”
• RIPE NCC’s only reference to LIR’s assignment
• Contact persons– can be multiple reference nic-hdls (may be a role object)– admin-c
• responsible for the network, able to make decisions
– tech-c• technical setup of the network
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 46
• Wait for approval from <[email protected]> prior to assignment and registration
• Decide on the range of within your address space– classless assignment on bit boundary
• Update local records– archive original documents with assignment

Creating Database Objects
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 48
Creating person Object
• Check if person object exists in RIPE DB– whois {person’s name; email address}
– only one object per person
• Obtain and complete a template whois -t person
– -v (verbose)
Send to <[email protected]>
• Each person object has unique nic-hdl

Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 51
<[email protected]> Responses
• Successful update– acknowledgement
• Warnings– object accepted but might be ambiguous– object corrected and accepted
• Errors– object NOT corrected and NOT accepted– diagnostics in acknowledgement
• If not clear send questions to<[email protected]>• Include error report
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 52
Creating Network Object
• inetnum– insert the address range in the ‘network template’
approved by hostmasters
– keep the same netname attribute
– in change attribute use current date• or leave out the date completely
• Send to <[email protected]>– with the keyword NEW in the subject line
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 53
Check Your Database Data
• Before you notify the customer– whois [customer’s IP range]– whois [customer’s netname]
– whois -m [your allocated IP range]• will show your first level customer(s) network(s)
– whois -L [customer’s IP range]• will show your own data

Current Address Space UsageEvaluation
• Are there any previous assignments?– ask customer
• Querying the RIPE Database– whois.ripe.net
• exact match
– http://www.ripe.net/ripencc/pub-services/db/• full text search using glimpse• whois web interface
• Can request be fulfilled with previous assignment?
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 61
Private Address Space• RFC-1918 (Address Allocation for Private Internets)
• Suitable for– partial connectivity– limited access to outside services
• can use application layer gateways (fire walls, NAT)
• Motivation– saves public address space– allows for more flexibility– security

PI Request
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 65
PA vs. PI Assignments• Provider Aggregatable
• customer uses addresses out of your allocation
good for routing tablescustomer must renumber if changing ISP
• Provider Independent• customer receives range of addresses from RIPE NCC
customer takes addresses when changing ISPpossible routing problems
• Make contractual agreements– ripe-127
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 66
Requesting PI Space
• LIR sends request on behalf of PI customer• Complete ripe-141 as usual• Differences:
#[Request Overview Template]#PI-requested: YES
#[Network Template]#status: ASSIGNED PI
• Explain why the customer wants PI – aware of the consequences?
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 67
Evaluation of PI Request
• Conservative estimates– will NOT get more addresses (then needed) to prevent
routing problems• Classless • Assignment is only valid as long as original
criteria remain valid (ripe-185)
• After approval– RIPE NCC assigns a block from own range– RIPE NCC puts assignment in database
with RIPE-NCC-HM-PI-MNT

Renumbering
… is easy!
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 70
When to Send Renumbering Request?
• Customer(s) changing providers– already using address space– returning PA addresses to OldISP – renumbering to the PA range of NewISP
• Changing from PI (or UNSPECIFIED) to PA
• Only if amount is above LIR’s AW
• Procedure made easier to encourage renumbering
• More info: http://www.isi.edu/div7/pier/
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 71
Renumbering Request• Complete ripe-141 request form
• Double check current addresses in DB– whois -L <customer’s IP range> => UpstreamISP inetnum– whois -m <UpstreamISP range>
• Show how addresses were used• Show how new addresses will be used
• Time frame guidelines - 3 monthsaddress-space-returned: 195.100.35/24 to UpstreamISP1 in 20000901194.200.70/24 to UpstreamISP2 in 20001001...
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 72
Renumbering Many Customers
• If all ‘1-1’ renumberings– include all in one request form
• making procedure easier
– separate inetnum and addressing plan for each• “50% utilisation” guideline
• If not ‘1-1’ (customer will need more addresses)– send one request per customer
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 73
After the Return Date
• If you are the “new” ISP for this customer– encourage your customer to renumber their whole
network to your address space
• If you are the “old” ISP of this customer– make sure you remove data from RIPE Database
• Hostmasters send regular reminders

Assignment Window Policies and Procedures
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 76
Assignment Window Policy
• Assignment Window– maximum amount of address space LIR can assign
without prior approval of the NCC initially AW equals zero gradually raised
• Why necessary?– support to LIRs during start up
– familiarisation with RIPE NCC procedures
– align criteria for request evaluation
– maintain contact between LIRs and RIPE NCC
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 77
Initially: AW=0
• SendEVERY customer’s request
and
EVERY request for assignment to your own infrastructure / network
to the RIPE NCC for evaluation
• Separate request forms needed• Do not send too many at the same time
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 78
When is AW Size Raised
• Understood procedures• Complete NCC documentation
• Experience– with RIPE Database– different policies– evaluating and processing requests
Not always automatically approach us
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 79
When is AW Size Lowered
• New staff need training
After negative auditing report
To enforce payment
To find out the AW size– asm-window line

New allocation
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 85
Allocation Procedures
• ‘Slow Start’– first allocation /20
• LIR announces the whole prefix
– size of future allocations depends on current usage rate• presumably enough for next two years • not always contiguous
• Motivation for ‘slow start’– fair distribution of address space– keeps pace with customer base growth– slows down exhaustion of IPv4 address space
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 86
Motivation for ‘No Reservations’ Policy
• Def.: Address space set aside for future use • Reservations may never be claimed
– customers may need more (or less) address space than is reserved
• Administrative convenience not catered for
• Fragments address space =>– requesting new allocation appropriate when
previous allocated space used ~ 80% !
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 87
Requesting New Allocation
• Send request to <[email protected]> • NOT ripe-141 form• NEWBLOCK in subject line
– summary of addresses assigned / free– list assignments of the last allocation
Suggested format:
Allocation: 195.35.64.0/19 assigned: 7372 free: 820 Range Netname
195.35.64.0 - 195.35.65.191 BLUELIGHT-1

...
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 88
Evaluation of New Allocation Request
• Are LIR’s records consistent with • RIPE NCC’s local records • RIPE database
– RIPE NCC wants to see 3 random requests
• Are all assignments valid?• within AW• correct netname attribute & the date
• Quality of RIPE DB records• up-to-date person & role objects• no overlapping inetnum objects
• Tool available: asused-public
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 89
Prior to Making New Allocation
• If inconsistencies are found– LIR will be asked to correct data first – AW is reviewed
• When data is corrected or deadline for correction is set– RIPE NCC
• allocates new block to LIR updates the DB
• LIR announces new prefix

Reverse Delegation Procedures
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 94
What is Forward and Reverse DNS Delegation ?
• Forward Delegation– enables naming of IP hosts on the Internet– hierarchical authority for domain registration
• organisational structure
• Reverse Delegation– enables association of IP addresses with domain names– hierarchical authority for reverse zone
• depends on who distributed the address space
– reverse delegation takes place on octet boundaries (classful)

Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 96
Why Do You Need Reverse DNS Delegation ?
• All host-IP mappings in the DNS (A record) should have a corresponding IP-host mapping (PTR record)
• Failure to have this will likely– block users from various services (ftp, mail)– make troubleshooting more difficult – produce more useless network traffic in general
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 97
Overview of the Request Procedure
• LIRs have to request reverse delegation• /24 zones are delegated
– to LIR / end-user – as the address space gets assigned
• Steps valid assignment of address space /24 reverse zone setup
on LIR or end-users nameserver(s), or both send domain object to <[email protected]>
• include Reg-ID
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 98
“Valid” Assignment
• According to ripe-185 policies Within “Assignment Window”
- or approved from RIPE NCC Hostmaster
• inetnum object registered in RIPE Database– netname attribute is NCC's only reference if
assignment approved • do NOT change netname without notifying
this is mentioned when we approve your IP requests
– registered after the approval date
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 99
/24 Reverse Zone Setup Recommendations
• At least two nameservers required– one nameserver setup as primary– at least one other as secondary
• SOA values reasonably RFC1912 compliant• Nameservers not on same physical subnet
– preferably with another provider
• Serial numbers YYYYMMDDnnn format

< /24 Delegations
Reverse delegation is also possible for a /24 shared by more customers
=> NOT reason for classfull assignments
• RIPE NCC reverse delegate authority for the entire /24 to LIR– procedure and requirements the same as for /24
• If customer wants to run own primary nameserver– LIR delegates parts as address space gets assigned– use CNAME to create an extra point of delegation
(RFC-2317)

Autonomous System
• Definition: a group of IP networks run by one or more network
operators which has a unique and clearly defined routing policy
• RIR is allocated a range of AS numbers by IANA– 16 bit number
• RIR assigns unique AS number– for LIR or for the customer
* AS number, routing policy and originating routes are registered in the Routing Registry
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 109
How To Get an AS Number ?
• Complete request form: ripe-147 – aut-num object template
• contact person(s)
mntner object template– address space to be announced with this AS#
• Send to <[email protected]>– web syntax check: http://www.ripe.net/cgi-bin/web147cgi
• Being multihomed and routing policy are mandatory!

Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 126
Notification / Authorisation
• notify attribute (optional)– sends notification of change to the email address
specified
mnt-by attribute & mntner object– objects that contain mnt-by must pass the
authentication rules in the mntner object
Hierarchical authorisation for inetnum & domain objects– mnt-lower attribute
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 127
How To Protect DB Data
• Read documents (ripe-157, ripe-189) choose authentication method
Create mntner object
• Existing objects must be changed– include mnt-by attribute referencing mntner object
• When creating new objects – include mnt-by attribute referencing mntner object

Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 134
Reverse Delegation of Multiple /24
– for range of consecutive zones – represented in single inetnum object
• Shorthand notation for domain attributeinetnum: w.z.x.0 - w.z.y.255 212.73.10.0-212.73.15.255
domain: x-y.z.w.in-addr.arpa 10-15.73.212.in-addr.arpa
• Submit as one domain object• Processed separately• Separate response
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 135
Reverse Delegation of /16 Allocation
• If a LIR has a /16 allocation, the RIPE NCC can delegate the entire reverse zone to the LIR
• Requirements and procedures the same as /24, except– /16 domain object– three nameservers needed– ns.ripe.net a mandatory secondary
• After delegation LIR– should continue to check sub-zone setup before further delegation– recommended use of the inaddr robot TEST keyword or web
check
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 136
Changing Delegation
• Change the nserver lines in domain object– submit domain object to <[email protected]>
• To change contact details in domain object– submit updated object to <[email protected]>
• Deleting a delegation is automatic– include delete attribute to the exact copy of the object– send to <[email protected]>
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 137
Common Errors
• DB / request inconsistency
(netname attribute, update date)• IP addresses instead of names of nameservers
in domain object• Trying to get reverse delegation for /19
allocation– has to be on octet boundaries– send request for each /24 as it becomes used
• DNS setup (RFC-1912)
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 138
Changes With New Robot
• Requests accepted only with Reg-ID• No RIPE DB updates necessary• No zone transfer necessary• Deletion requests handled (almost) automatically • Request for each zone processed separately• Successfully passed checks cached • Shorthand notation for ranges of objects• Delegation checks possible via web interface • LONGACK and CHANGE keywords no more

Routing Registry
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 142
Internet Routing Registry (IRR)• Goals of the IRR
– consistency and stability of routing – enable development of tools to use information
• Local IR responsibilities– register policy information in RR– maintain RR information
• Regional IR responsibilities– assigning Autonomous System Numbers– consistency checking of data– maintenance of RR support tools
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 143
Internet Routing Registry
• Globally distributed DB with routing policy information– provides a map of global routing policy– shows routing policy between any two ASes– allows simulation of routing policy effects– enables router configuration– provides contact information
• RIPE Routing Registry– subset of information in RIPE database– syntax description in ripe-181

Administrivia
• Audit• Billing• Closing
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 156
Audit Motivation
• Audit Activity is a service– requested by the community– ensure equal treatment– LIR can ask for an audit
• Help LIRs to– keep RIPE Database tidy– keep up-to-date with new policies
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 157
Audit Activity
• Described in ripe-170• Initiated for
– infrequent contact with the RIPE NCC
– random selection
– referral by Hostmaster
– (anonymous) LIR complaint
• Audit procedure– LIR answers list of questions
– RIPE NCC check database
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 158
Audit Steps
• When LIR responds– discuss the issue(s) & try to resolve them– review AW size
• If LIR does not co-operate– send reminders & phone – still no reaction
• further actions taken
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 159
Billing Procedure• LIRs pay yearly fee (based on size)
– ripe-198
• If payment is late - email reminders– 1st phase - 4 weeks after the invoice
• no action taken
– 2nd phase - 2 weeks afterwards • lower AW to 0• mnt-lower on allocation
– 3rd phase - 2 weeks afterwards• service level NONE
– if still no payment …
• Discuss payment / invoices– <[email protected]>

Closing / Takeover of the Registry
1) Registry closes completely
2) Registry takes over another registry and one closes
3) Registry takes over another registry and both remain open
4) Non-registry takes over a registry ...
• Contact <[email protected]> for details• address space issues• billing issues
• new service agreement • No need to change current Reg-ID
• neither after company changes the name• additional ‘start-up’ fee is being charged

IPv6
Local Internet Registries Tutorial . RIPE 37, Amsterdam 12-15 2000. . http://www.ripe.net 163
Why IPv6?
• Next generation protocol– scalability -- 128 bits addresses – security– dynamic hosts numbering
• Interoperable with IPv4• simple and smooth transition
– hardware vendors– applications

IPv6 Allocations
• Request form (ripe-195)• ”Slow start”
– first allocation to a TLA Registry will be a /35 block • representing 13 bits of NLA space
– additional 6 bits reserved by RIR for the allocated sub-TLA for subsequent allocations
• Reverse Delegation of an IPv6 Sub-TLA– http://www.ripe.net/reverse/
• IANA allocations– APNIC 2001:0200::/23 (12 subTLAs)– ARIN 2001:0400::/23 ( 4 subTLAs)– RIPE NCC 2001:0600::/23 (19 subTLAs)
