++ 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
