We pick j.root-servers.net, one of the 13 root servers (1), and ask it about sennui.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that sennui.com is delegated to two name servers, including ns1.netart.pl (3), so we ask that one and get the following answer:
Sennui.com is a domain controlled by three domain name servers at netart.pl. All three of them are on the same IP network. Incoming mail for sennui.com is handled by seven mail servers at googlemail.com and google.com having a total of 61 IP numbers. There are 24 duplicated IP numbers. Some of them are on the same IP network. Sennui.com has four IP numbers (216.239.32.10, 216.239.36.10, 216.239.34.10, 216.239.38.10). All four of them are on different IP networks.
