I am at a friend's house, and using my laptop to connect to the Internet on his wireless router.

Is it possible to set my IP, so it would be the same as on my home network?

He has the same Internet provider as me. I use Windows NT.

OK this is my situation: my dad does not want me to hang out at my friend's house all the time (I study at another town). He can somehow check my IP at home (he knows about computers and I don't) and when I connect and write emails from my friend's house, he knows that I have been at my friend's. So I hope I can send him an email from my friend's house and if he checks (looks up on the internet) where it is from, it will say my home IP address.

Yes, you can set your IP to be the same as your home network. The question is if you still want to be able to access the internet or other devices on the network ;) – slhck Aug 5 '12 at 15:27
Do you mean you want to set your local IP on his LAN to be the same as your local IP on your LAN? Or do you mean you want your Internet IP connecting to the Internet from his LAN to be the same as your Internet IP connecting to the Internet from your LAN?

if you're also using a router, then it's possible if your router and your friend's router config to same net (eg. but if you're connect to internet directly (such as via cable modem), then you can't. – LiuYan 刘研 Aug 5 '12 at 15:47
He can probably judge by external IP address as well anyhow. You and your friend would need the same ISP. :) Perhaps just don't use the Internet while at your "friend"'s house (wink wink nudge nudge). ;) – Ƭᴇcʜιᴇ007 Aug 5 '12 at 16:47
We have the same internet service provider. Would i have to change settings if i want to show my own IP adress. is it difficult to do so? – Mitja Polanec Aug 5 '12 at 17:20
