DNS delegation of majdah.com updated: May 25, 2013 8:11:41 AM
We pick c.root-servers.net, one of the 13 root servers (1), and ask it about majdah.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that majdah.com is delegated to five name servers, including ns1.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
Two thirds of the several thousand of domains that use name server group 1 point to IP group 1 (example: maqilyahoo.com, justyahoo.com and chatyahoofrance.com ). Worth noting is that three quarter of the host names that point to IP group 1 use name server group 1.
The name server ns2.yahoo.com
There are several thousand of domains that use the name server ns2.yahoo.com.
