GTM w/o BIND and NS Records
"You say that when the client asks for the NS set of wip.site.com, it receives back A records. Normally, it should receive an NS set with a set of glue A records in the Additional section. Is that what's happening, or is it really just getting A records?"
Thanks for the response! Yes, the response has three NS records in it, AND the three related IP addresses. Which are the IP addresses of the GTM. Glue, yes. This is when the client discovers the GTM IPs. We do not do recursion, so the next query after this is directly to the GTM. I expect this be an A Record Query against the GTM for the host FQDN (host.wip.site.com). However, it is another NS lookup for that full name, just now against the GTM. When this times out, The client then tries NS lookups for (.wip.site.com). When this times out, The client then tries NS lookups for (host.wip.site.com), and stays stuck there in a loop, looking for these two NS records on the GTM. It appears to ignore any TTL that came with the successful NS lookup against the DNS servers. It seems to want a successful, or maybe autorative, NS response from GTM before proceeding to looking up and A Record.
Thanks for the response!!!
