We pick i.root-servers.net, one of the 13 root servers (1), and ask it about odsol.com and learn that com is delegated to 13 name servers (2), so we ask m.gtld-servers.net where we learn that odsol.com is delegated to four name servers, including dns2.odsol.com (3), so we ask that one and get the following answer:
Odsol.com is a domain controlled by four domain name servers at odsol.com and odsol.net. Two domain name servers have the same IP number. Two of them are on the same IP network. Incoming mail for odsol.com is handled by five mail servers at odsol.com and zero.spam having a total of 30 IP numbers. There are four duplicated IP numbers. Some of them are on the same IP network. We are missing the IP:s of one server: zero.spam. Odsol.com has one IP number (67.196.63.196), but the reverse is sun.robustserver.com.
