DNS delegation of d-dns.com updated: May 23, 2013 9:04:34 PM
We pick k.root-servers.net, one of the 13 root servers (1), and ask it about d-dns.com and learn that com is delegated to 13 name servers (2), so we ask f.gtld-servers.net where we learn that d-dns.com is delegated to two name servers, including ns2.bnc.net (3), so we ask that one and get the following answer:
D-dns.com is a domain controlled by three domain name servers at bnc.net. All three of them are on the same IP network. Incoming mail for d-dns.com is handled by two mail servers at dtag.de and mailomat.net. Both are on different IP networks.
