The Vista DNS Query Behaviour is described here: http://www.microsoft.com/technet/network/ipv6/vista_dns.mspx
"- If the host has only link-local or Teredo IPv6 addresses assigned, the DNS Client service sends a single query for A records. - If the host has at least one IPv6 address assigned that is not a link-local or Teredo address, the DNS Client service sends a DNS query for A records and then a separate DNS query to the same DNS server for AAAA records. If an A record query times out or has an error (other than name not found), the corresponding AAAA record query is not sent." I don't know why they don't do any AAAA query if you have a teredo address (which is globally routable), but the rest sounds reasonable. -- IPv6 should be disabled by default https://bugs.launchpad.net/bugs/24828 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
