We pick d.root-servers.net, one of the 13 root servers (1), and ask it about faceboo.com and learn that com is delegated to 13 name servers (2), so we ask l.gtld-servers.net where we learn that faceboo.com is delegated to two name servers, including b.ns.facebook.com (3), so we ask that one and get the following answer:
Faceboo.com is ranked #842324 world wide and is hosted on a server in Menlo Park, CA, United States. It has 1493 inlinks. It has 1 organic keywords.
