resolver issues: AAAA in ipv4 only environment

[Guido van Rooij]

It seems there are a lot of broken named's on the Internet that do not
answer to AAAA queries.

I have a noteboo that sometimes is, and sometimes is not IPv6
connected. However, I do not want to wait too long when on IPv4 only
networks. So I would like to eiother have a resolveroption to
specify not to ask for AAAA records, or have a smart resolver
that figures out that it doesn't need to query AAAA records when
only link local IPv6 addresses are found. 

I do not want to carrie around 2 kernels (one with and the other without
ipv6).

I'd like to have see some comments on this...
