aol.com is a domain owned by AOL, Inc. Aol, or America Online as they were previously called, is an american global brand company. The former software giant now specializes in technology development and investments, having acquired both Techcrunch.com and the Huffington Post, since Aol's separation from Time Warner in 2009.
We pick j.root-servers.net, one of the 13 root servers (1), and ask it about aol.com and learn that com is delegated to 13 name servers (2), so we ask i.gtld-servers.net where we learn that aol.com is delegated to four name servers, including dns-06.ns.aol.com (3), so we ask that one and get the following answer:
aol.com is a domain owned by AOL, Inc. Aol, or America Online as they were previously called, is an american global brand company. The former software giant now specializes in technology development and investments, having acquired both Techcrunch.com and the Huffington Post, since Aol's separation from Time Warner in 2009. Aol.com is a domain controlled by four domain name servers at aol.com themselves having a total of five IP numbers. All five of them are on different IP networks. Incoming mail for aol.com is handled by four mail servers also at aol.com having a total of 22 IP numbers. Some of them are on the same IP network. Aol.com has five IP numbers (205.188.101.58, 207.200.74.38, 205.188.100.58, 64.12.89.186, 64.12.79.57). Some of them are on the same IP network.
All of those use the four name servers dns-01, dns-02, dns-06 and dns-07.ns.aol.com together, hereafter referred to as "name server group 1", (example: nullsoft.net, revolutionfanboy.com and aol.ca ). Worth noting is that eight percent of the domains that use name server group 1 point to IP group 1.
More than one in seven of them point to IP group 1 (example: madonnamusic.com, aolicon.com and compuserve.fr ). Worth noting is that all of the host names that point to IP group 1 use name server group 1.
The name server dns-01.ns.aol.com
There are several thousand of domains that use the name server dns-01.ns.aol.com.
