In the slashdot article
here. Verisign, the company who bought network solutions (the company the US government put in charge of running all .com and .net TLD's), put a wildcard at the end of .com and .net TLD's.
What this means? if you ping
www.fooooooooooo.com, you'll get a response, even though
www.fooooooooooo.com does not exist. The response will be from 64.94.110.11 [sitefinder.verisign.com].
Indeed, any .com or .net domain that you type in, if it does not exist, instead of an error, you'll get redirected to sitefinder.verisign.com
Another little tidbit. If you send an email to a non-existant .com or .net domain, you'll get the wrong error (user unknown instead of host unknown), since the mail will be sent to verisign's server.
Abuse of power?
