DNS delegation of luxyahoo.com updated: May 19, 2013 6:59:03 PM
We pick m.root-servers.net, one of the 13 root servers (1), and ask it about luxyahoo.com and learn that com is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that luxyahoo.com is delegated to five name servers, including ns5.yahoo.com (3), so we ask that one and get the following answer:
The five name servers ns1, ns2, ns3, ns4 and ns5.yahoo.com together
Three quarter of the several thousand of domains that use name server group 1 point to IP group 1 (example: htmyahoo.com, verifiedyahoo.net and editcompanionyahoo.com ). Worth noting is that most of the host names that point to IP group 1 use name server group 1.
