DNS delegation of yahoo.com.bd updated: May 19, 2013 6:59:11 PM
jamuna.btcl.net.bd. dns.bd. surma.btcl.net.bd.
We pick k.root-servers.net, one of the 13 root servers (1), and ask it about yahoo.com.bd and learn that bd is delegated to three name servers (2), so we ask jamuna.btcl.net.bd where we learn that yahoo.com.bd is delegated to three name servers, including ns3.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 about ninety domains that use name server group 1 point to IP group 1 (example: dlsyahoo.com, emailyahoomail.com and findchatingyahoo.com ). Worth noting is that nine percent of the host names that point to IP group 1 use name server group 1.
