Class C Network

[garybeafl]

HI
Can anyone tell me what a Class C Network is and why they be trying to access my home computer at 10:00AM on a Sunday morning? They are in Secaucus, N.J. and I am in Brandon, Fl.

What is the exact message you are receiving to tell you this is happening?

Zone Alarm sent me to Whois? and it gave me the name and address of the company that was trying to access my PC. It also gave me the name of the Coordinator and his 800 number. I dont want to ID him here for fear of reprisal. I went to Google and it gave me a list on names one of which was this company and Google said this was a list of Class C network companys. Anyone know what a Class C network is? Sorry about not getting back sooner but the wife had me trimming the outdoor Christmas tree.

Gary, I would beleive that the "class C Network" is the actual OWNER (is ISP) of the IP addy (individual who is "leasing" the address) that was trying to "hack" your system. ZoneAlarm should have listed a ip# in conjuction with this "hit". from WHOIS what you got was the OWNER of the IP address block. (group of addresses). This was probably just a port scan. Make note of the IP addy and the date and time and if you continue to recieve this same "hack/hit" then send an Email to the the Owner/ISP of the Ip addy. If you want more indept information feel free to email me the IP addy and I can tell you who to email your complaint to

Gary, a class C address is given by the Internet Naming Authority (or its like) to companies. It's not an important piece of info (I mean the fact that it's class C- the IP # is important)other that it tells you that it is a small to medium sized company.
Class A for huge companies Class B for big companies. An address like 319.125.124.3 is made up of 32 bits (8 bits per section) The Internet Naming Authority would give you 319.125.124.0 as an address and the last 8 bits (where the 0 is) is for you to divide into subnets and individual IP addresses.
As for the attack I would contact the company, it could be that some unauthorized individual accessed this persons computer station to carry out a port scan.
The company may be interested in what you have to show them.

Thanks Mntsnow
I think for now I will just keep watch on it. After looking at the print out I think you are correct. Thanks again.
