I have read your funnies and they are great and with that in mund, I believe you are a man who can take a good question without becoming un-glued.
This isn't about computers, Just about the GURU setting them up named LEO NOTENBOOM. The question is, Why do you put your name all as one word and leave out the L in the Bloom part? Like, Leo, Not in bloom? Looks to me that you are in bloom with a face full of whiskers. I am jealous of that too, because I cannot grow a full beard as dark and straight as yours. And I am only 39. being born in 1927. Thanx

One other way to get someone's name and address is if the IP is for their web site server, it's a dedicated server, and you use WhoIs to look up the registrant info for their domain.

Now, given that almost every registrar offers anonymous registrations and few people surf from their web server, it's a fringe case, but it can happen.

What's more troubling, though, are cross-site tracking cookies used by major ad networks like DoubleClick.

A few years back there was news that DoubleClick was going to link up people's identifiable information with their IP addresses (when they logged in at certain sites, the DoubleClick cookie would register the login), so that as people traversed different sites where DoubleClick served ads, DoubleClick could track their surfing habits and pair those up with their names.

This caused a firestorm of anger among netizens and many major sites that used DoubleClick were deluged with angry e-mails.

Eventually, DoubleClick dropped the plan, but it's not impossible that some ad network could quietly do it. That's why many "spyware" killers also kill cookies from major ad networks.

Following up on Ed Carver's comment that "you can use WhoIs to look up the registrant info for their domain:"

Is there a way to do this on a volume basis?

For example, create a text file & load it into WhoIs, or elsewhere?

If I enter 129.34.20.80 into ARIN WhoIS, I get IBM. I'd like to be able to find out the names of all companies where the IP is for their web site server.

Thx, Bob

I was wondering whether a person could be tracked after posting on a forum. After all, most sites record the visitors IP address.

The closest I could get from your IP address is "Instituto Costarricense de Electricidad y Telecom" in Costa Rica. I would have to contact them to find out more. It's doubtful that they'd tell me anything. So technically you can be tracked, if the people tracking you have law enforcement on their side, but most people do not.

Do one person has the same IP address using the same computer?.. or does the IP address changes constantly like after going in and offline.

Lyn, It depends on what ISP (Internet Service Provider) ure using. Some use a static IP which means your IP address is always the same and some use an dynamic IP meaning the IP changes every time you sign on to the internet.
