Does IP Address Reveal my Physical Location?
Are You Invisible Online?
It's true that your IP address is no secret. It's a basic part of internet communication protocols to send your IP address whenever you connect to another site, request a web page, chat, play an online game, etc. Without your IP address, the computer on the other end wouldn't know where to send the reply.
But that doesn't mean that Evildoers can find your house if they know your IP address. Each time you go online (if you have dialup) or each time you start your computer (if you have cable or dsl) you will be assigned an IP address, randomly selected from a pool of IP's assigned to your Internet service provider (ISP).
WHOIS Your ISP
So a person MIGHT be able to get a general idea of your geographic location, based on your IP address, by doing a lookup on the WHOIS database, but that will only tell them the physical location of your ISP -- not YOUR home address.
And if you use a large regional or nationwide ISP, the IP lookup probably reveals nothing of interest. For example, if you are an AOL subscriber, your IP address lookup will show the location as Dulles, Virginia -- regardless of where you live.
When The Law Comes A Knockin'
Of course there is an exception to every rule. If Joe or Jane User calls your ISP and wants to know who was using a certain IP address last Tuesday, the ISP will tell them to go away. But if an officer of the law hands your ISP a court order to reveal that information, they must do so. Your ISP's logs will enable them to determine which customer was using a certain IP address on a certain date & time, and they must reveal that information if a court has found probable cause that a crime was committed by that person.
But for the truly paranoid (or the criminally inclined) there are ways to surf the web anonymously. The Anonymizer service will act as a proxy between you and your ISP, and they claim that your information cannot be subpoenaed because they do not store it.
What About Email Addresses?
The same concepts apply to your email address. The part that follows the "@" sign is your ISP's domain name. And given the domain name, one can determine the ISP's physical location, but nothing personally identifying about the email user without a court order.
Web-based email accounts are not truly anonymous, either. Even if you don't provide your real name when signing up, they can capture your IP address and track you through your ISP if necessary.
Other Considerations
It's much more likely that you or your children will reveal your physical location the old fashioned way -- by just blurting it out. Kids who chat or play online games should be reminded often that they should never reveal any personal information, including their last name, phone number or home address.
Oh, and if you have any spyware or viruses on your system, all bets are off. These things are designed to violate your privacy. If you need help with scanning your system for spyware, adware and other unwanted pests, see my article on free anti-virus and anti-spyware software for details on how to protect yourself from those risks.

hai,
It's nice.We can find the geolocation of an ip address by using ip-details. It's also useful for me.

Bob, I decided to give "Anonymyzer" a 7 day FREE trial. A question I do have is: What does my ISP now SEE that I have installed "Anonymyzer"? Keep in mind that I had to give my Cable Modem's & Router's MAC addresses years ago when I first signed up with my ISP. Does "Anonymyzer" conceal those addresses as well as my CPU's IP? Since I am behind those devices, I DO CARE that the addresses of those DEVICES be concealed first since they lead to my node on my home LAN. Whether or not jerks see my IP address is immaterial really though that is a bonus in my case for Intranet privacy.
What does my ISP NOW SEE packet wise (MAC addresses included) once "Anonymyzer" is installed?
EDITOR'S NOTE: I'm almost certain your ISP will not see anything different, in terms of your IP and MAC addresses.

Bob,
Thank you for your timely reply. ;-)
I am fining out that the ISP is the one folks have to fear the most - not just the hackers in terms of privacy, information harvesting, and tracking etc... Products like "Anonymyzer" _claim_ that once one uses their product, that one is enshrouded in anonymous safety. How can that be? If ISP's still can access everyone's IP and MAC addresses everyone is still very very vulnerable, especially if Enforcement Officials are brought into the picture & summon your information from ISPs. "Anonymyzer" only spoofs one's IP address but beyond that what does it offer really since it does NOT offer complete anonymity? HOW can one achieve complete anonymity on the Web today?

Hello Bob. How are you doing? I was wondering, if I send an e-mail through a yahoo account just for info purposes and no crime has been committed, just an e-mail sent with a diff name other than my own, can the recepient get my IP address own their own? If so, how? If they can, what info can they get? I really appreciate your help!!
EDITOR'S NOTE: Yes, if you send an email using Yahoo, the recipient can see your IP address. In the full headers, there will be something like this:
Received: from [12.345.789.901] by web123.mail.sp1.yahoo.com
The number in the brackets is the sender's IP address. But why would you care? IP addresses are public information, and that's by design. Did you read the article on which you commented?

I had someone recently get my IP address since I posted on their message board and they posted it in public. Now lots of people have it. However, the IP they have is not my ISP's IP but instead my router's IP address. Is there anything I can do to change the IP address of my router? I have dynamic IP addresses from my ISP (roadrunner) and when I asked them they assured me they would not tell anyone who I am based on my IP ( I wonder if they even can if the person gives them the IP that is really for my router). So what can I do here to remain anonymous? Thanks very much!
EDITOR'S NOTE: The Internet is designed so that every site you connect with will see your IP address. It's not meant to be private, and you shouldn't be concerned if someone knows it. Knowing your IP address doesn't give anyone the power to hack into your computer, nor does it reveal who you are. BTW, if you have dynamic IP addresses from your ISP, then the address assigned to your router isn't really "yours". What you describe is the situation for 99% of all broadband users. Nothing to worry about here...

OK so may I make sure I have a complete understanding of this. The IP address which is associated with my router is not only mine but quite possibly many other people in my area? In other words, the IP I have might be the same as other people who use the same brand of router and have the same ISP as me? Many thanks! (BTW my fears are not for hacking but for someone to find out my name, home address, etc.. or for them to be able to say "since his IP is XXXXXXX, then this post HAS to be from his computer)

Hello,
I used my laptop to send a complaint through yahoo about my work at a local city goverment. They are now UPSET.
They are trying to find out who sent it. Can they trace me. Can they also trace me back to the same IP if I log in at my outlook mail from same laptop? Will yahoo or my dsl give me up? It was just a complaint one my manager but they are saying it was slander.
EDITOR'S NOTE: Yahoo and your ISP will not give up that info without a court order. However, if you sent an email through Yahoo, the recipient can look in the "full headers" to see the sender's IP address. If you send other emails from that same IP address (regardless of the email program used), the recipient COULD assume that you sent the other one. With dialup, you typically get a different IP address every time you logon. Not sure if that's the case with DSL.
