(dpns4,dpns3,dpns1,dpns2).dnsnameserver.org.
We pick d.root-servers.net, one of the 13 root servers (1), and ask it about alp4.com and learn that com is delegated to 13 name servers (2), so we ask g.gtld-servers.net where we learn that alp4.com is delegated to four name servers, including dpns4.dnsnameserver.org (3), so we ask that one and get the following answer:
Alp4.com is a domain controlled by four domain name servers at dnsnameserver.org. All four of them are on the same IP network. Alp4.com has one IP number (208.87.149.250), but the reverse is ?.
