OpenDNS, one of the Internet's most popular free DNS services, is now offering production-grade support for IPv6, an upgrade to the Internet's main communications protocol known as IPv4.
OpenDNS CEO David Ulevitch says he is launching the IPv6 service now to help website operators and networking firms prepare for World IPv6 Day, a 24-hour test of IPv6 that is scheduled for June 8. Sponsored by the Internet Society, World IPv6 Day has attracted more than 160 participants, including some of the Internet's leading content providers, such as Google, Yahoo and Facebook.
OpenDNS says it will participate in World IPv6 Day by having all of its Web sites support IPv6 by default on June 8.
OpenDNS said it was the first to offer a free DNS recursive service that supports IPv6. Recursive DNS services allow Internet users to find websites by typing in their domain names and pulling up the corresponding IP numbers. In contrast, authoritative DNS services allow website operators to publish their domain names and corresponding IP addresses to Internet users.
The IPv6 addresses for the OpenDNS IPv6 DNS Sandbox are: 2620:0:ccc::2 and 2620:0:ccd::2.
