(pdns2,pdns1).cscdns.net.
We pick e.root-servers.net, one of the 13 root servers (1), and ask it about vis-a-ball.com and learn that com is delegated to 13 name servers (2), so we ask a.gtld-servers.net where we learn that vis-a-ball.com is delegated to two name servers, including pdns2.cscdns.net (3), so we ask that one and get the following answer:
Vis-a-ball.com is a domain controlled by two domain name servers at cscdns.net. Both are on different IP networks. Incoming mail for vis-a-ball.com is handled by four mail servers at psmtp.com. All four of them are on the same IP network.
