We pick a.root-servers.net, one of the 13 root servers (1), and ask it about mail.datec.com.vu and learn that vu is delegated to four name servers (2), so we ask futuna.vanuatu.com.vu where we learn that datec.com.vu is delegated to two name servers, including ns10.zoneedit.com (3), so we ask that one where we see a CNAME from mail.datec.com.vu to wfb.zoneedit.com, so we have to start all over again. We pick i.root-servers.net, one of the 13 root servers (4), and ask it about wfb.zoneedit.com and learn that com is delegated to 13 name servers (5), so we ask b.gtld-servers.net where we learn that zoneedit.com is delegated to five name servers, including ns2.zoneedit.com (6), so we ask that one and get the following answer:
mail.datec.com.vu has two IP numbers (207.44.244.117, 64.34.164.16). Both are on different IP networks. This hostname cnames to wf.zoneedit.com. Koukl.com, cousinssubs.com, mborsuk.com,...
