We pick b.root-servers.net, one of the 13 root servers (1), and ask it about digex.com and learn that com is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that digex.com is delegated to two name servers, including mia01.digex.com (3), so we ask that one and get the following answer:
Digex.com is a domain controlled by two domain name servers at digex.com themselves. Both are on the same IP network. Incoming mail for digex.com is handled by six mail servers at verizon.com and verizonbusiness.com. Some of them are on the same IP network. Digex.com has one IP number (164.109.72.70), which also has a corresponding reverse pointer.
