Listen to the podcast: Getting all worked
up over IP tracing . Transcript A frequent question I get on Ask Leo! relates to IP addresses, and how much you can find out from one. "Publicly available information about an IP address can
typically only be traced as far as the ISP that owns it."
It get this from both sides. On one hand, I hear from people who are concerned that someone can track them down physically - perhaps find out their home address - based on their IP address. On the other hand, I also hear from people who want to find out who's at some IP address, because they're being contacted in some form, and that's the only bit of potentially identifying information they have to grab on to. Publicly available information about an IP address can typically only be traced as far as the ISP that owns it. If the IP happens to correspond to a registered domain name, then perhaps the domain registration might provide a little more information - or not. It's the ISP that assigns the IP address to an individual device on the internet. And a good ISP will not reveal to whom they've allocated the address to just anyone. In fact, my assumption is that legal action and possibly law enforcement of some sort would be required for an ISP to release that information. In many cases, the information is even more obscure. Instant Messaging conversations typically do not include the IP address of the participants. If, for example, you're attempting to track down who is IM'ing you, you'll probably need the help of the IM provider such as AOL, MSN, or one of the others. Same for most web-based email providers and messages - not all contain the IP address of the actual originator, so you'll need the provider's help to track it down. Again, that's not help I'd expect to get without legal action. In reality, I consider that great news. While it's important that that information be made available when it's appropriate, meaning legal action, I think we all want our privacy too. The ISPs and service providers are important gatekeepers of that privacy. So don't go expecting to find a lot of information based on an IP address unless you've got a valid and defensible reason. And conversely, while technically it is possible to track down an IP address to a specific machine and location, it's not easy, and it's not something that the general public can do. Related:

It's fun or usefull when you track IP addresses, because you can make an idea about the person, country, maybe state, or if it is from an organization or big company. http://www.ipgp.net gives accurate information and map.

No way to know. It depends on the ISP.

WHile it is possible to find an approximate location from an IP address in an email header, email originating from AOL accounts only seems to trace back as far as the AOL server.
Is there a way to find an approximate location of the specific computer used to send the mail?

As stated in this and several articles on this site:
- - if you're an average user: no
- - if you're the ISP that owns the IP address: probably
So normal people typically need to get law enforcement involved and court
orders to trace an IP to a computer.
