We pick m.root-servers.net, one of the 13 root servers (1), and ask it about com.ch and learn that ch is delegated to seven name servers (2), so we ask a.nic.ch where we learn that com.ch is delegated to two name servers, including ns01.vtx.ch (3), so we ask that one and get the following answer:
Com.ch is a domain controlled by two domain name servers at vtx.ch. Both are on the same IP network. Incoming mail for com.ch is handled by one mail server at com.ch themselves. We are missing the IP:s of one server: mail.com.ch. Com.ch has one IP number (144.85.10.78), but the reverse is www.com.ch.
