Hi everyone. I think I've got a host resolution mixup. Here are the symptoms. Domains registered with network solutions still show the old ip address for ns1 and ns2.purplecat.net even though the forward lookup for those names changed more than 3 months ago. Domains registered at other registrars don't seem to have this problem. I'm in the process of moving my primary name servers from one isp to another, and I _do_ have some issues with my reverse resolution: new isp ns1.purplecat.net --> 208.133.44.46 rack.purplecat.net --> 208.133.44.46 208.133.44.46 --> rack.purplecat.net old isp mail.purplecat.net --> 209.16.228.148 209.16.228.148 --> ns1.purplecat.net I was under the impression that i could 'get away' with such a configuration, and that dns would continue to work even if the reverse lookup of a name server did not match. Is this not the case? TIA, Peter Brezny purplecat.net test# dig @G.GTLD-SERVERS.net ns1.purplecat.net ; <<>> DiG 8.3 <<>> @G.GTLD-SERVERS.net ns1.purplecat.net ; (1 server found) ;; res options: init recurs defnam dnsrch ;; got answer: ;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 6 ;; flags: qr rd; QUERY: 1, ANSWER: 1, AUTHORITY: 2, ADDITIONAL: 2 ;; QUERY SECTION: ;; ns1.purplecat.net, type = A, class = IN ;; ANSWER SECTION: ns1.purplecat.net. 2D IN A 208.133.44.46 ;; AUTHORITY SECTION: purplecat.net. 2D IN NS ns1.purplecat.net. purplecat.net. 2D IN NS NS2.purplecat.net. ;; ADDITIONAL SECTION: ns1.purplecat.net. 2D IN A 208.133.44.46 NS2.purplecat.net. 2D IN A 208.133.44.47 ;; Total query time: 74 msec ;; FROM: test.skyrunner.net to SERVER: G.GTLD-SERVERS.net 192.42.93.30 ;; WHEN: Mon Apr 29 20:44:16 2002 ;; MSG SIZE sent: 35 rcvd: 115 Peter Brezny purplecat.net To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
