[mega-snippage]
Speaking from the point of view of someone serving authoritative DNS
data, rather than running a cache server for users, there is one thing
above all required to reduce the number of unnecessary queries:
** All traces of BIND 8.3.3 and 8.3.4, and all code that shares their
AAAA/A6 nameserver lookup bug, must be purged from the net completely. **
In the two and a half years or so since I first noticed this issue, the
extent of any improvement has been slight. This isn't really surprising;
how many people even know that those versions are broken? How many people
would care, even if they knew, about the fact that they are generating
unnecessary queries to other people's DNS servers?
