Hi guys. I have recently transferred several virtual domains to another web hosting service, but my nameserver does not see the domains on look up (none of the ones I've transferred to this one hosting service). The interesting thing is that I have transferred other domains to other hosts and havent had this problem so I'm having difficullty accepting that its my problem, but hey it could be I guess. I will outline what I see below: ok heres a for instance: I do a whois chesserrealty.com from my nameserver and I get Record last updated on 21-Jul-98. Record created on 17-Oct-96. Database last updated on 20-Aug-98 04:21:41 EDT. Domain servers in listed order: NS1.GRNCO.NET 208.21.151.1 NS2.GRNCO.NET 208.21.151.2 ok, so then I do a nslookup for www.chesserrealty.com from my name server I get No match for "WWW.CHESSERREALTY.COM". of course I cant ping em or traceroute them since I cant look them up :) Now the interesting part: I use nslookup off of another server... like this: ns# nslookup www.chesserrealty.com ns2.mci.net Server: ns2.mci.net Address: 204.70.57.242 Non-authoritative answer: Name: www.chesserrealty.com Address: 208.21.151.2 so now this is weird. these domains have been transferred for quite a long long time. I got to looking in my log files and I see lots of entries like this: Aug 15 14:26:56 ns named[11593]: "151.21.208.in-addr.arpa IN NS" points to a CNAME (ns1.grnco.net) Just out of curiosity, I ping ns1.grnco.net and I get ns# ping ns1.grnco.net PING hal.grnco.net (208.21.151.1): 56 data bytes 64 bytes from 208.21.151.1: icmp_seq=0 ttl=52 time=124.032 ms 64 bytes from 208.21.151.1: icmp_seq=1 ttl=52 time=123.728 ms 64 bytes from 208.21.151.1: icmp_seq=2 ttl=52 time=123.395 ms so this is what I _think_ is happening: the name server @ grnco is really named hal.grnco.net, from the lookup and pinging. ns1 is a cname for hal... the reverse records in their in-addr.arpa mapping is pointing the NS entries to a CNAME which is a no-no from what I've seen / read. Would my name server be refusing their "broadcasts" due to this? what else can I try or look at?
