We pick l.root-servers.net, one of the 13 root servers (1), and ask it about googlescholar.com and learn that com is delegated to 13 name servers (2), so we ask e.gtld-servers.net where we learn that googlescholar.com is delegated to four name servers, including ns4.google.com (3), so we ask that one and get the following answer:
The four name servers ns1, ns2, ns3 and ns4.google.com together
About one in six of the more than a thousands domains that use name server group 1 use mail server group 1 (example: dartlang.org and ourstories.org ).
