Thanks a lot for the help Forrest. For freebsd isp related problems, I've always had helpful support from this list, I'm glad to see that the positive supportive environment still exists here. Here's an example of the problem I am seeing: Two domains both using ns1 and ns2.purplecat.net as their name servers. domains registered at a registrar _other than_ networksolutions don't list ip addresses related to ns1 and ns2.purplecat.net for example: whois agrnews.org Domain Name: AGRNEWS.ORG Registrar: CORE INTERNET COUNCIL OF REGISTRARS Whois Server: whois.corenic.net Referral URL: http://www.corenic.net Name Server: NS1.PURPLECAT.NET Name Server: NS2.PURPLECAT.NET Updated Date: 24-apr-2002 domains registered at networksolutions.com provide incorrect ip addresses for ns1 and ns2.purplecat.net even thought he forward lookup for these hosts works fine, _and_ modifying the information for barbarafield.org with the correct ip addresses at networksolutions does not fix the problem, even though it claims that the update went through successfully: whois barbarafield.org Domain Name: BARBARAFIELD.ORG Registrar: NETWORK SOLUTIONS, INC. Whois Server: whois.networksolutions.com Referral URL: http://www.networksolutions.com Name Server: NS1.PURPLECAT.NET Name Server: NS2.PURPLECAT.NET Updated Date: 05-nov-2001 ... Domain servers in listed order: NS1.PURPLECAT.NET 209.16.228.148 NS2.PURPLECAT.NET 209.16.228.149 However: dig @a.gtld-servers.net. ns1.purplecat.net ; <<>> DiG 8.3 <<>> @a.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 I've sent an e-mail to networksolutions with the same question but have not heard back from them (surprise).

In theory everything should work right. In reality nameservers occasionally get confused about their role in life and stop working. And when this occurs it usually is a problem with the local nameservers. I think Peter's other (implied) guess might be that there is something seriously broken in the forward delegation of your domains, which (if it is the case) should be taken up with the appropriate registrar. If you post the actual domains and what brokenness you are seeing (perhaps one that works vs one that doesn't work) generally someone on here will do a couple of digs and be able to tell you where to look for the cause. Saying "I'm doing something nonstandard, will this break anything?" will probably get you more of the responses you got... I.E. we're not experts at every concievable DNS mangling, try some other list. - Forrest W.
