This issue has been reported over 4 years ago, and has become a serious real-life problem for organisations. IANA (global supply) ran out of IPv4 addresses in February 2011. Shortly after that APNIC (Asia-Pacific supply) ran out. In September 2012 RIPE NCC (Europe/Middle-East/parts of Asia) ran out of IPv4 addresses.
Being able to run an IPv6-only network is increasingly important. Sure, hacks like NAT64/DNS64 exist. They form performance bottlenecks and single-points-of-failure in networks. Having native IPv6 support on an important service like security.ubuntu.com is important. Relying on 3rd party NAT64 boxes can even be a security risk (they would be the perfect place to do man-in-the-middle attacks). The Canonical Sysadmins and the Ubuntu Security Team are notified of this issue, so I hope they take action as soon as possible. This is something that should have been fixed last year. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/241305 Title: security.ubuntu.com not accessible in IPv6 (AAAA record missing in the DNS) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-website/+bug/241305/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
