The thing is that there are a lot of these sites. Watching the log on the other side of my DNS server it looks like it is sending requests to vanguard's dns server, but not getting any replies. Is there some way I can lower the timeout for IPV6 DNS lookups or maybe disable them? Or is there some change I can make to mozilla to minimize the impact of sites like these? Hmm. Looking at the FreeBSD resolver code, it doesn't look like there is some convenient way to do this. Maybe something like, try the AAAA lookup, but if we don't get any reply in a short timeout, try an A lookup. If we get a reply to that, then log the site as probably not conforming to the RFC.
