I want to like IPv6. I do. But I'm seriously considering turning off IPv6 support from our servers. First off, I'm using djbdns internally and it doesn't support AAAA records. So we really aren't using it internally. But today I noticed that we have a lot of traffic to our DNS cache, and started to investigate. Turns out that every DNS request would start with one for the AAAA record. Ah, no luck. Maybe you forgot the search domain? Let's retry that DNS request with that tacked on. Failed again? Meanwhile, lets simultaneously try for the AA record then. Repeat.
++ on what everyone else has said about this being a problem with the way you run your DNS infrastructure, instead of an actual IPv6 problem. Without reasons listed for why you use djbdns, I can't really adequately comment, but: on our net we're using unbound as caching DNS servers with pretty good success, and pdns with dynamic backends (the backends are custom in-house stuff) as our authoritative DNS. Short of issues now and then with the backends, it works pretty well. -J
