Abstract

• The Numbers

- IPv4

- ASN

- IPv6

• The Policies

- IPv6



Introduction To The Numbers: IPv4

• A “/8” is 16,777,216 addresses

• There are 256 * /8s

• Minimum allocation to LIRs: /21

- 2048 addresses



Introduction To The Numbers: IPv6

• Millions of times more addresses!

- When compared to IPv4

• Focus is more on networks

- Not individual addresses



Introduction To The Numbers: ASN

• Autonomous System Numbers

- Routing Identifier

• Initially 65,536 ASNs available

• Now billions more: ASN32

- Introduction phase until 2010

- Available from 1 January 2007

IPv6 Allocation Policies

• Current policy

• Policy proposals



IPv6 Allocation Criteria• You

- are an LIR

- not an End Site

- plan to provide IPv6 connectivity to aggregated ‘customers’, who are assigned /48s

- plan to assign 200 /48s within two years

• Minimum initial allocation size /32

- more if needed, calculated with HD ratio

• 602 Allocations, 4000+ Members!



IPv6 Assignment and Utilisation Requirements (2005-08)

• Aims to increase the useful lifetime of IPv6- period in excess of 100 years

- no further allocation policy changes are anticipated

• Changes:- allow assignment size to be chosen by LIR

- “End Site” definition for HD ratio calculation to /56

- HD ratio from 0.8 to 0.94

• /32 Allocation:- old: HD ratio 0.8, /48 assignments: 7132 /48s needed (11%)

- new: HD ratio 0.94, /56 assignments: 6,183,533 /56s needed (37%)

• (24,154 /48s)



Provider Independent (PI) IPv6 Assignments for End User Organisations (2006-01)

• Currently:

- No PI in IPv6

- Only possible to multihome with LIR allocation

- Multihoming a requirement for some non-LIR organisations

• Temporary policy: until three years after technical alternative is available



IPv6 Address Allocation and Assignment Policy (2006-02)

• Changes to the policy:

- organisations without external customers can also qualify

- allow assignment size to be chosen by LIR

- remove “plan for 200 assignments”
