We pick h.root-servers.net, one of the 13 root servers (1), and ask it about google.us and learn that us is delegated to six name servers (2), so we ask f.cctld.us where we learn that google.us is delegated to four name servers, including ns4.google.com (3), so we ask that one and get the following answer:
Google.us is ranked #3518 world wide as google.org and is hosted on 57 servers in Mountain View, CA, United States. It has gained 16715 inlinks over a period of 14 years.
