How can I find who owns an IP address?

[PADemD]

My firewall detected someone who was trying to access my network.

3. Thank you

Will this also help for a MAC address?

4. Doubtful, do you have the MAC address for the intruder?

Do you have another computer in your home?

Or perhaps your own computer is running software to check your own computer.

It happens.

5. I don't have a MAC

The firewall said "College of Miseracordia" and a MAC address.

8. you don't have the actual intruder's MAC

unless the culprit is DIRECTLY connected to your network/wifi. if not, his real MAC was lost as the IP that tried to connect to you got transferred over several different networks to get to you.

FYI a MAC is the unique hardware Address assigned to a network device when directly connected to a network. it is only relevant within the initial network..

more than likely the MAC you got was of your own gateway..

2. You might also have posted something somewhere that....

is being read by the spybots or the google robots, and some robot somewhere is trying to figure out who you are, or what you are associated with.

This could mean you posted something like an essay or a statement or two or three, and it was unique, that is: the words you used were unique or common for today, yesterday.

Your Google robots out there are searching to find stuff on your IP address, see if you are some publisher, some congress person, if you have something else to say.

Google and other robots do these things 24 hours a day, 365 days a year. They look everywhere.

Or, of course, if you threatened the USA, the President, someone in power, other spies could be looking at you. Just saying...

6. You might try NetLab 1.4

I find it quite useful for a number of things.

7. This works for me.

9. "College of Misericordia" is a real school

in Dallas,PA maybe it came from a dorm room. what's the IP?

10. Just called the IT Dept at Misericordia

They are going to call me back.

14. Probably a "bot"

Someone has an infected computer looking for more computers to infect.

You can find who owns an IP address by using whois lookup tools like WhoisXY.com

15. Try one of the standard WHOIS registries. But it seems to be legal to hide behind a proxy,

like domainsbyproxy.com, so an informative search is not guaranteed
