GENERAL OVERVIEW OF LACNIC LABS MEASUREMENTS

IPv6 penetration• Monitoring since 2014• Per-country penetration stats (Google,

Akamai)• Websites with AAAA records• v6 Embryos: ccTLD domains which have

AAAA on w6, www6, ipv6, v6 records butdo not have on www (yet)

IPv6 penetration

Source: stats.labs.lacnic.net (raw data for Google and Akamai)

IPv6 regional study• In conjunction with CAF and collaboration from

Cisco 6lab• Deep study about the transition to IPv6– ICAv6 Index considering

• Routing ( % of v6 prefixes seen in RT)• Network core (Potential transit ASes over v6)• Content• End users (Google, APNIC)

– Economic alternatives modeling to help agents responsible of v6 deployment make better decisions

– Field study and interviews– Success cases: Bolivia, Ecuador, Peru (and Brazil)

IP addresses: v6 visibility

Assignments are Allocations present at the routing table

Disaggregated allocations are counted only once.

IP addresses: v6 visibility

IP addresses: v6 visibility

IP addresses: v4 exhaustion models

CONNECTIVITY MEASUREMENTS IN THE LAC REGION

Connectivity• Based on RTT measurements• 32 bytes ICMP pings (IPv4 only, 10 samples)• Point at regional Speedtest servers• Originated from 21 countries• During ~1 year• ~200 measurements per hour• Based on SpeedChecker platform (Maxmind

lite database and Mozilla Geolocation API forgeolocation information)

Connectivity• What is connectivity exactly?• Country-based regional latency graph• 21 nodes• 201 edges• Performed community-based clustering• 4 main clusters

Connectivity latency clusters

Source: TeleGeography

Primary conclusions• Region divided in 4 main clusters (with

geographic correlation)• Good inter-country connectivity stands for

~150 ms ICMP pings (closer to 200 for weakly connected regions)

• Inter-cluster connectivity stands for ~200 ms ICMP pings

Additional conclusions• Connectivity is usually intuitive• Graph GàH transformation

(edge weight w à 1/w)• Cluster based on 1/w• Look for “dis-connectivity” latency clusters

Additional conclusions� Region 2⁃ Brazil⁃ Costa Rica⁃ Belize⁃ Peru

��Region 3⁃ Ecuador⁃ Suriname⁃ Paraguay⁃ El Salvador⁃ Panama

��Region 1⁃ Chile⁃ Argentina⁃ Honduras⁃ Trinidad & Tobago⁃ Mexico

��Region 0⁃ Dominican Republic⁃ Guatemala⁃ Colombia⁃ Venezuela⁃ Bolivia⁃ Uruguay⁃ Cuba

Additional conclusions• Far north vs down south (predictably)• Some interesting cases– Between oceans• Ecuador and Suriname

– (and neighbors)• Argentina – Chile• Colombia – Venezuela• Brazil – Peru
