We pick h.root-servers.net, one of the 13 root servers (1), and ask it about dnsnode.se and learn that se is delegated to nine name servers (2), so we ask f.ns.se where we learn that dnsnode.se is delegated to two name servers, including slave.sth.netnod.se (3), so we ask that one and get the following answer:
Dnsnode.se is a domain controlled by two domain name servers at netnod.se having a total of three IP numbers. All three of them are on different IP networks. Incoming mail for dnsnode.se is handled by one mail server also at netnod.se having a total of two IP numbers. Both are on different IP networks.
