Standrad statement coming from this level3.net.
But firewalls tell the story differently and log every entry made on your computer, every request send to your computer and every request you send out to either get to your mail server or the WWW. When these servers start attempting to get to protected files on your computer and your firewall puts up a stop on the ip address such as 126.96.36.199, which translates to resolver1.level3.net one starts figuring out what is going on with level3.net.
When you call their 800 number you start figuring out a few more things that maybe you didn't know about level3.net such as fiber optics being phone lines and the like along with a few other very interesting bits of infomation of concerning the internet.
