We pick b.root-servers.net, one of the 13 root servers (1), and ask it about sicef.net and learn that net is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that sicef.net is delegated to two name servers, including ns1.ispfr.net (3), so we ask that one and get the following answer:
Sicef.net is a domain controlled by two domain name servers at ispfr.net having a total of four IP numbers. Some of them are on the same IP network. Incoming mail for sicef.net is handled by two mail servers also at ispfr.net. Both are on the same IP network. Sicef.net has one IP number (195.114.18.144), but the reverse is cl2.ispfr.net.
The two mail servers mx3 and mx4.ispfr.net together
All of the more than a thousands domains that use mail server group 1 use name server group 1 (example: all-for-design.com, stmartinducanigou.org and ledude.net ). Worth noting is that a third of the domains that use name server group 1 use mail server group 1.
The IP number 195.114.18.144
There are several hundred of host names that point to the IP number 195.114.18.144.
