How to configure NT DNS for internet?

By acattr ·
I'm an admin at a new place. They have two NT servers handling all Dns requests for the entire network's intranet and Internet needs. It also handles all requests for the company .com domain name. These two servers have IP addresses on the internet and so do all the clients(I know, big risk). BUT

What I can't seem to understand is how are these two servers able to resolve internet DNS queries? I am thinking it must connect to some higher level DNS servers. But I can't seem to see wherethis is set in the dns admin. Also if so, is my company paying some provider to allow us to handle our own Dns requests?

Check to see if your hosting a forwarding DNS or if You have host name for the Company providing your internet, this will more than likley tell you how everything is setup.
Check your DNS manager or go to DNS Folder and look at how the BIND files are setup they will give you some more INFO.

Pick up a bind/dns book some time, it will help you to understand it. Typically some registrar will record the nameserver(s) for your domain, pointing to the IP's of your 2 NT servers. This is done when you register your domain, and is part of you domain registration costs. Usually some much every couple years. All this is placed in the root servers, you can see these roots in the root level of the cache in the DNS gui or the cache.dns in your NT system32/dns directory assuming all defaults forthe install are in place. This information is pulled from the root servers to DNS servers everywhere and updated occasionally depending on the TTL for the DNS servers for your domain. On the flip side your DNS servers pull and cache this informationfrom the root servers as well for resolution of other domains. You can see what site are being hit by looking at the cache. Through the cache for your domain you can see the IPs of the nameservers, typically a NS record. Hope it helps.

Regards,
