We pick m.root-servers.net, one of the 13 root servers (1), and ask it about optimist-arch.ru and learn that ru is delegated to five name servers (2), so we ask f.dns.ripn.net where we learn that optimist-arch.ru is delegated to two name servers, including ns1.expired.r01.ru (3), so we ask that one and get the following answer:
The two name servers ns1 and ns2.expired.r01.ru together
One quarter of the several hundred of domains that use name server group 1 point to the IP number 109.70.26.36 only (but not 194.85.61.78 ) (example: bashmetall.ru, buds.ru and dese.ru ). Worth noting is that two of the host names that point to the IP number 109.70.26.36 only (but not 194.85.61.78 ) use name server group 1.
