(ns09,ns10).domaincontrol.com.
We pick d.root-servers.net, one of the 13 root servers (1), and ask it about admindot.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that admindot.com is delegated to two name servers, including ns09.domaincontrol.com (3), so we ask that one and get the following answer:
Admindot.com is a domain controlled by two domain name servers at domaincontrol.com having a total of four IP numbers. All four of them are on different IP networks. Incoming mail for admindot.com is handled by two mail servers at admindot.com themselves having a total of three IP numbers. There are two duplicated IP numbers. Two of them are on the same IP network.
