We pick e.root-servers.net, one of the 13 root servers (1), and ask it about ghandours.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that ghandours.com is delegated to four name servers, including ns3197.dns.dyn.com (3), so we ask that one and get the following answer:
Ghandours.com is a domain controlled by four domain name servers at dyn.com. All four of them are on different IP networks. Incoming mail for ghandours.com is handled by six mail servers at google.com having a total of 63 IP numbers. There are 13 duplicated IP numbers. Some of them are on the same IP network.
