We pick c.root-servers.net, one of the 13 root servers (1), and ask it about photoids.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that photoids.com is delegated to two name servers, including ns1.iplt.twtelecom.net (3), so we ask that one and get the following answer:
Photoids.com is a domain controlled by two domain name servers at twtelecom.net having a total of four IP numbers. Two of them are on the same IP network. Photoids.com has one IP number (204.124.80.33), but the reverse is ?.
