What Is an IP Address?
IP address stands for Internet Protocol address. It is a unique identifying number that allows every internet-connected device to send and receive information. It’s entirely public, and it can be used to identify you when you do things online. Your IP info can tell people what ISP you’re with, and even what city you’re in.
Think of it like your car’s license plate or your home’s zip code and door number: everyone has one, it’s unique to you, and it can be seen by anyone.
To find your IP address and location, simply use our IP lookup tool at the top of this web page. You’ll see your IPv4 address, IPv6 address, ISP, and your physical location. You can use this to learn your real IP address or to check that your virtual private network (VPN) is working.
Because a VPN will hide your public IP address with a different one, try using this tool first when your VPN is off, then again once you’ve connected to a VPN server. If you’re shown two different IP addresses then your VPN is working. You can find full instructions for checking your VPN later on in this article.
