You do this exactly the way an outside DNS server would do it. You first of
all ask one of the root servers (DNS servers are pre-configured with the
root servers).
server a.root-servers.net [198.41.0.4]

When you request mydomain.com, it will return all the servers that serve the
..com domains. Then select one of those:

server A.GTLD-SERVERS.NET [192.5.6.30]

When you request mydomain.com, it will return all the servers that serve the
mydomain.com domain.

> mydomain.com
Server: [192.5.6.30]
Address: 192.5.6.30

Name: mydomain.com
Served by:
- ns1.mydomain.com
64.94.117.195
mydomain.com
- ns2.mydomain.com
216.52.121.233
mydomain.com
- ns3.mydomain.com
66.150.161.130
mydomain.com
- ns4.mydomain.com
63.251.83.74
mydomain.com

Select one of those and ask the question again:

> mydomain.com
Server: ns1.mydomain.com
Address: 64.94.117.195

Name: mydomain.com
Address: 216.34.94.184


Done!
