We pick k.root-servers.net, one of the 13 root servers (1), and ask it about syngenta.jobs and learn that jobs is delegated to seven name servers (2), so we ask f5.nstld.com where we learn that syngenta.jobs is delegated to two name servers, including dns2.cscdns.net (3), so we ask that one and get the following answer:
The two IP numbers 165.160.13.20 and 165.160.15.20 together
There are several thousand of host names that point to IP group 1.
Two thirds of those use name server group 1 (example: bloombergyes.net, reddelights.net and clerkenwelllondon.com ). Worth noting is that a third of the domains that use name server group 1 point to IP group 1.
