(ns2,ns1).above.com.
We pick k.root-servers.net, one of the 13 root servers (1), and ask it about e.xphotos.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that xphotos.com is delegated to two name servers, including ns2.above.com (3), so we ask that one and get the following answer:
E.xphotos.com is a domain controlled by two domain name servers at above.com having a total of four IP numbers. Some of them are on the same IP network. E.xphotos.com has one IP number (69.43.160.151), which is the same as for xphotos.com, but the reverse is ?.
Most of the several hundred of host names that point to the IP number 69.43.160.151 point only to that ip number (example: ifi.biz, ipos.ca and mxp.ca ).
The two name servers ns1 and ns2.above.com together
There are more than hundred domains that use name server group 1.
