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.

total 129385446 40846541 1473921 2905526 1697
Total registered domains with AAAA records: 1473921
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.

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: Fri Nov 20 00:11:30 PST 2009
ASes using IPv4 and IPv6: 1744
ASes using IPv4 or IPv6: 33149
Percentage of ASes (IPv4 or IPv6) running IPv6: 5.4%
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.)
IPv6 rDNS Nameservers Last Polled: Fri Nov 20 02:19:34 PST 2009
IPv6 rDNS Nameservers with an IPv4 address: 2239
IPv6 rDNS Nameservers with an IPv6 address: 876
IPv6 rDNS Nameservers reachable via IPv4 (ping or dns): 1949
IPv6 rDNS Nameservers reachable via IPv6 (ping or dns): 732
IPv6 rDNS Nameservers reachable via IPv4 or IPv6: 2026
IPv6 rDNS Nameservers reachable via IPv4 and IPv6: 655
Percentage reachable IPv6 rDNS Nameservers reachable via IPv6: 36.1%
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): 373
IPv6 rDNS Nameservers where IPv4 and IPv6 are the same speed (within 1ms): 91
IPv6 rDNS Nameservers where IPv4 is faster than IPv6 (by more than 1ms): 191
IPv6 rDNS nameservers where IPv6 is as fast or faster than IPv4 (within 1ms): 464
Percentage of IPv6 rDNS Nameservers where IPv6 is as fast or faster than IPv4 (within 1ms): 70.8%
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.
