We pick e.root-servers.net, one of the 13 root servers (1), and ask it about co.com and learn that com is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that co.com is delegated to two name servers, including ns1.co.com (3), so we ask that one and get the following answer:
Co.com is a domain controlled by one domain name server at co.com themselves. Incoming mail for co.com is handled by one mail server also at co.com. Co.com has one IP number (216.195.78.38), which also has a corresponding reverse pointer.
