In summary, what he means is this: You have a (perhaps legacy) DNS server running as dns3.tensor.gdynia.pl (RRs snipped for brevity): pearl# dig aaaa dns3.tensor.gdynia.pl dns3.tensor.gdynia.pl. 21682 IN AAAA 2001:4070:101:2::1 ...which appears to be the same IP address as your workstation. pearl# dig AAAA wojtek.tensor.gdynia.pl wojtek.tensor.gdynia.pl. 4732 IN AAAA 2001:4070:101:2::1 ...however, any attempt to gather information from dns3. simply fails, due to your administrative policy (named not allowing outside networks). I'm willing to bet that you will see attempts from 2607:f118::b6 (or ::b7) in your workstation logs as rejected for AAAA lookups. I don't see any reference to dns3. in the WHOIS, so perhaps it has been removed recently. Any provider who still has this dns3 server listed as a possible authoritative name server may round-robin to it and produce the logs on your workstation you are witnessing. It is very possible that this server is still listed as a NS for the domain and I just didn't look hard enough for it. FYI (IMHO), this type of question would be better suited for freebsd-net@. You would likely have far more eyes on your question over there by people who focus primarily on this sort of thing. Steve
