firewall showing 30 connections from windows 2003 DNS server to other

[realized]

since i have deployed a new machine running windows 2003 server, my firewall is reporting that i usually have some 20 or so connections opened from my windows server to other DNS servers port 53.

i understand that my server needs to make queries to the outside, but 30 connects running 24/7 ? seems excessive no?

dns server is running fine, and dns shows no errors.

it has been doing this for a week now.

what IP's is it connected to? are they internal IPs or external?
