teradata.com.
(sus-sdcdns01ext,sus-hdcdns01ext).teradata.com.
We pick f.root-servers.net, one of the 13 root servers (1), and ask it about td.teradata.com and learn that com is delegated to 13 name servers (2), so we ask c.gtld-servers.net where we learn that teradata.com is delegated to two name servers, including sus-sdcdns01ext.teradata.com (3), so we ask that one and get the following answer:
Td.teradata.com is a domain controlled by two domain name servers at teradata.com. Both are on the same IP network. Incoming mail for td.teradata.com is handled by two mail servers also at teradata.com. Both are on the same IP network.
