DNS delegation of in-addr.com updated: May 25, 2013 3:01:38 PM
We pick m.root-servers.net, one of the 13 root servers (1), and ask it about in-addr.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that in-addr.com is delegated to four name servers, including ns2.he.net (3), so we ask that one and get the following answer:
In-addr.com is a domain controlled by four domain name servers at he.net having a total of eight IP numbers. Some of them are on the same IP network. Incoming mail for in-addr.com is handled by one mail server at in-addr.com themselves having a total of two IP numbers. Both are on different IP networks.
