We pick c.root-servers.net, one of the 13 root servers (1), and ask it about coptech.com and learn that com is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that coptech.com is delegated to five name servers, including dns4.name-services.com (3), so we ask that one and get the following answer:
Coptech.com is a domain controlled by five domain name servers at name-services.com. All five of them are on different IP networks. Incoming mail for coptech.com is handled by three mail servers also at name-services.com. All three of them are on different IP networks. Coptech.com has two IP numbers (98.124.199.1, 98.124.198.1). Both are on different IP networks.
