Global IPv6 Deployment Progress Report

By Mike Leber

This page was developed in order to provide metrics for global IPv6 deployment. These statistics are updated daily. Please send questions, comments, or bugs to mleber@he.net

The tools for this report were developed while working on a paper titled "Going Native" about Hurricane's experience of adding extensive native IPv6 peering as a result of a core router and backbone upgrade.

Top Level Domains with IPv6 support

The root nameservers contain NS records listing the nameservers for the Top Level Domains (TLDs) and A and AAAA glue records to get to those nameservers. Top level domains include domain name suffixes such as .com .net .org .us .ca etc. Each TLD has specific authorative nameservers. To support IPv6 these nameservers should: Generated by parsing the root zonefile to get a list of TLDs and their associated nameservers, querying for AAAA records for the names of those nameservers and checking for AAAA records in the root zone for those nameservers.

Registered domains with AAAA records

Generated by querying for A (IPv4) and AAAA (IPv6) records for all domains in the listed TLDs (top level domains). Demonstrates growing use of AAAA records for the primary domain name of websites and other Internet services. (Note: we would like to add any TLDs that will allow us access for daily downloads.)

Total registered domains with AAAA records: 4786872

This tells you the number of registered domains that have added IPv6 for their primary domain, for the set of TLDs above, which is a partial listing based on what TLDs we could get access to. It does not include subdomains i.e. ipv6.google.com, which means our number is a lower bound and that the number of IPv6 enabled domains is even higher.

Eventually the really important number here is the total number of domains returning AAAA records. However, right now a large amount of the domains included in this number are the result of SEDO (search engine domain optimization) parking operations. By looking at the gradual increase in the people that have AAAA glue in the TLD zone files for their authorative nameservers we can tell that the trend of individual companies enabling IPv6 for their websites and other infrastructure is upwards.

Top 1000 Usenet Servers with IPv6 support

Generated by parsing the top 1000 usenet servers (from Top 1000 Usenet Servers) and querying for A and AAAA records. Note: Due to how the usenet protocol works not every listed usenet server has a direct addresses (some usenet server names are not fully qualified domain names).

Networks Running IPv6

We can measure the percentage of networks running IPv6 by comparing the set of ASes in the IPv6 routing table to those in the combined set of IPv4 and IPv6.

IPv4 and IPv6 RIBs Last Parsed: Wed May 22 01:04:55 PDT 2013

IPv4 ASes: 44339

IPv6 ASes: 7092

ASes using only IPv4: 37372

ASes using only IPv6: 125

ASes using IPv4 and IPv6: 6967

ASes using IPv4 or IPv6: 44464

Percentage of ASes (IPv4 or IPv6) running IPv6: 15.9%

IPv6 rDNS Nameservers running IPv6

One amusing measure of IPv6 deployment to ask the question: What percentage of IPv6 reverse DNS servers are reachable via IPv6?

(ping tests and dns queries run from a server on Hurricane Electric's IPv4 and IPv6 backbone in Fremont, California.)

Percentage reachable IPv6 rDNS Nameservers reachable via IPv6: 48.7%

IPv6 Performance

Actually, the reason we looked at IPv6 reverse DNS servers was to get some hosts on both IPv6 and IPv4 so that we can compare IPv6 vs IPv4 latency.

IPv6 rDNS Nameservers where IPv6 is faster than IPv4 (by more than 1ms): 1818

IPv6 rDNS Nameservers where IPv4 and IPv6 are the same speed (within 1ms): 311

IPv6 rDNS Nameservers where IPv4 is faster than IPv6 (by more than 1ms): 700

IPv6 rDNS nameservers where IPv6 is as fast or faster than IPv4 (within 1ms): 2129

Percentage of IPv6 rDNS Nameservers where IPv6 is as fast or faster than IPv4 (within 1ms): 75.3%

Top Websites Running IPv6

A very quick way to measure IPv6 deployment for websites is just to check for a AAAA record in DNS.

Alexa provides an approximate list of the most popular sites on the web.

In the report below, the raw domain is the base domain, such as free.fr, which does not have an AAAA record (at the time of this writing. However www.free.fr *does* have a AAAA record. So we check both.

Another convention is to add an AAAA using ipv6 as a subdomain, i.e. ipv6.google.com. The reason so many domains show up as having A records for "ipv6." subdomains is because many domains use wildcard records in DNS which respond to queries for any subdomain.
