internal dns server: primary dns setting should be???

[oROEchimaru]

on the internal dns server... its ip is 192.168.100.8

should the primary dns server (the tcp/ip NIC setting) be 127.0.0.1 or 192.168.100.8 (itself?)

which one should the dns server point to for itself?

all other servers use 192.168.100.8 as their primary dns server.

127.0.0.1 is home. It points to itself. So, in your circumstance, 127.0.0.1 IS 192.168.100.8.

DNS server should point to itself for DNS resolution.

just use 127.0.0.1. That way if you ever change the IP address of your DNS server you won't have to change that.

Generally speaking, trying doesn't result in irrevocable data loss, unless you're trying delete queries / switches to rm in *nix.
