Thread: is it easy to find out another person's IP address

1) I checked my IP address, and I find out it is the same with another person's IP address.
--- I just google "my ip", then the system tells me "your public IP address is XXXXXXXX"

we are in the same house.

so it is not my real IP address.


2) the another way is to send a email to me,
if I reply, you can find out my IP address.


any other ways?

Your IP is dynamic and could be going through a proxy. Easiest way to find out your IP is:

in Windows CMD type ipconfig

or in Linux and OSX in shell type ifconfig

You should see a picture above with your public IP address. We always send our IP address out in any web transaction. To find out your private address, follow the post above.

There's no such thing as "your IP address." Each network layer you pass through has a different address. The one you get from Google is the one to the router or modem your computers are hooked to.

ok, I change my question to how another person can find out my IP?

By putting a picture, like a posted above, in their post and having you view it, even if its a 1x1 invisible picture.

Everyone can find out your IP. Think of the internet as mail, you send out letters with a return address, so their responses can come back to you. That return address is your IP. People know you who are. Get over it. Just think of chatting on the Internet like going to your local pub. People see your face and its okay.

thanks for the answer.

I just want to find out how it works.

The return address analogy is a good way to think of it. And since you presumably want to read the web pages you're trying to load, there's no way to avoid it. (You send out a self-addressed stamped envelope every time you open a new page. The server uses that to send you the contents of that page.)

There are public and private IP addresses. Public IPs are devised by the global Internet authorites, and handed to all ISPs in all countries.

Each customer whether house of business gets a single public IP address. So this is the "what's my IP?" thing from Google. And as said this is dynamic and changes often. I guess provided people have Internet access, it doesn't matter.

Your private IP address is set by your router, either static (set by you) or DHCP (set automatically by the router). So your public IP could be, say, 98.123.144.233, but your private is 192.168.1.233.

In your case, well as it's a house your public IP address would be the same. However, you should have unique private IP addresses.

Well a person cannot set his or her public IP, unless they get permission from their ISP. but a private one can be anything in the designated private ranges. For most home users though, the 192.168.1.x range is enough.

Yes, this is very technical, but then I work with IP systems so this is why lol..
