Subject: Broken DNS prevents IPv6 deployment

Hi all,

We've noticed that some sites like news.bbc.co.uk are running broken DNS 
servers that return NXDOMAIN for AAAA queries rather than NOERROR with 
zero answers.  The NXDOMAIN reply indicates that there are no records of 
any type for the requested name, which is clearly not true since A records 
exist and are returned with an A query.

Unfortunately, this means that applications that attempt AAAA queries are 
unable to resolve addresses that reside within these broken servers.  And 
that includes WinXP with the IPv6 stack enabled.  We would like to deploy 
IPv6 on Windows XP machines here, but our users complain loudly when they 
are not able to access BBC.

Has anybody found a workaround for this problem?  Judging by newsgroup 
messages, BBC has known about this problem for months and has neglected to 
fix it.  At the very least, does anybody have an idea of how widespread is 
this problem?  -Nathan
