Who Is...American Digital Network ?

[Aljaydu]

Hello everybody...
I'm using Sygate PFW. My ISP is SBC. For the past two weeks or so, I've noticed American Digital Network "snooping" or maybe "sniffing" my pc. I've looked them up and they don't relly mean anything to me. haven't heard of them before.
Here's the "who is " info:

They're scanning my ports:
Somebody is scanning your computer.
Your computer's UDP ports:
33452, 33453, 33454, and 33456 have been scanned from 206.251.233.109..
It's the same IP address.
I went to PC Flank and checked those ports and they are stealth.

Any Ideas?

Thanks in advanced.

All I can get is they're part of AIS which appears to be affiliated with SBC/Pacific Bell. It appears to be just an internet services company. You can call their customer service number here.

More then likely some internet backbone of somesort ...

Look for there webistie on google a lot of these sites it turns out are plainly sites providing the backbones to services on your ISP's I think this is bull crap though they have no reason to be port scanning your pc they sure the hell dont like it when you port scan them why should it be good for them and not us we are the folks paying for the network.
