We pick c.root-servers.net, one of the 13 root servers (1), and ask it about aspentec.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that aspentec.com is delegated to two name servers, including ns1.p21.dynect.net (3), so we ask that one and get the following answer:
Aspentec.com is a domain controlled by five domain name servers at uu.net, aspentech.com and aspentec.com. Two domain name servers have the same IP number. Two of them are on the same IP network. Incoming mail for aspentec.com is handled by two mail servers at mxlogicmx.net and mxlogic.net having a total of five IP numbers. There are two duplicated IP numbers. Some of them are on the same IP network. Aspentec.com has one IP number (192.135.137.71), but the reverse is www.aspentech.com.
