Your IP address is your network’s address on the internet. Finding it takes seconds, but understanding which address you found matters: your public IP, your private IP, and your VPN’s IP are three different numbers. This guide explains all three.
Public versus private IP
Your public IP is the address the internet sees, assigned by your internet provider to your whole network. Every device in your home shares it. Your private IP is the address your router gives each device inside your home network, such as 192.168.1.105. Websites see only the public one; your router uses the private ones to tell devices apart. Think of it like an apartment building: the public IP is the building address, the private IP is the apartment number.
Step-by-step: find your public IP
- Open an IP informer tool in your browser. Your public IP appears immediately.
- Note whether it is IPv4, four number groups, or IPv6, a longer address with colons. Most networks still show IPv4 first.
- Read the extra details the tool shows: your approximate city, your internet provider, and your timezone.
- If you use a VPN, the tool shows the VPN server’s address, not your real one. That is expected, and it is how you confirm the VPN is working.
- For your private IP, check your device settings instead: on Windows, run ipconfig; on Mac, check Network settings; on a phone, check the Wi-Fi details.
Why your IP changes
Most home connections use dynamic IPs, which change periodically when your router reconnects or your provider reassigns addresses. That is normal and harmless. A changing IP is also why blocking by IP is unreliable for identifying a person: the address may belong to someone else tomorrow.
Privacy notes
Your public IP reveals your approximate city and your provider, but not your name or street address. Still, avoid posting it publicly, since it can be used to target your network. If you need to share it for support, share it privately and only the part that is needed.

Quick tips
- Websites see your public IP; your router manages your private IP.
- A VPN changes the public IP a tool reports, by design.
- Never post your public IP in a public forum or screenshot.
Finding your IP is instant; understanding it takes a minute. Public for the internet, private for your home network, and a VPN’s address when one is active.
Frequently asked questions
Can someone find my home address from my IP? No. An IP reveals your approximate city and your provider, not your street address. Only your provider can link an IP to a subscriber, and it does so only under legal process. Still, avoid posting your IP publicly.
Why does my IP change every few days? Because most home connections use dynamic addressing: your provider reassigns addresses as routers reconnect. This is normal and harmless. Static IPs, which never change, are usually a business service.
What is IPv6, and why do I have two addresses? IPv6 is the newer, longer address format, created because IPv4 addresses ran short. Many networks run both, so a tool may show an IPv4 and an IPv6 address for the same connection. Either one identifies your network.
Worked example
Open an IP informer at home and it shows a public IPv4 address, your provider’s name, and your city. Open the same tool on your phone with Wi-Fi off, and it shows a different address belonging to your mobile carrier, possibly in another city. Both results are correct: they describe different networks. Connect a VPN and the tool shows the VPN server’s address instead. Three networks, three addresses, one device, which is why “my IP” always needs the context of which connection you mean.
