We pick f.root-servers.net, one of the 13 root servers (1), and ask it about mobile.ch and learn that ch is delegated to seven name servers (2), so we ask b.nic.ch where we learn that mobile.ch is delegated to two name servers, including dns47-2.mobile.de (3), so we ask that one and get the following answer:
Mobile.ch is a domain controlled by two domain name servers at mobile.de having a total of three IP numbers. All three of them are on different IP networks. Incoming mail for mobile.ch is handled by two mail servers also at mobile.de having a total of three IP numbers. All three of them are on different IP networks. Mobile.ch has two IP numbers (91.211.75.154, 194.50.69.154). Both are on different IP networks.
Three of them point to the IP number 194.50.69.154. Worth noting is that three of the host names that point to the IP number 194.50.69.154 use the name server dns45-2.mobile.de.
Three of them point to the IP number 91.211.75.154. Worth noting is that three of the host names that point to the IP number 91.211.75.154 use the name server dns45-2.mobile.de.
