DNS delegation of routing.se updated: May 25, 2013 10:37:26 PM
We pick b.root-servers.net, one of the 13 root servers (1), and ask it about routing.se and learn that se is delegated to nine name servers (2), so we ask d.ns.se where we learn that routing.se is delegated to two name servers, including dns9.telia.com (3), so we ask that one and get the following answer:
Routing.se is a domain controlled by two domain name servers at telia.com having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for routing.se is handled by one mail server also at telia.com.
