Your public IP is the address websites and online services see when your traffic reaches them. It is not the 192.168… number on your laptop. It is not a password. It is just the network label for the path you are using right now.
The fastest way to see it is to open a site that reports the address from the server’s point of view. On FindMyIP, that is the homepage. The number on that page is your current public IP for this browser request.
This guide is about how to find that address. It is not a deep dive into private ranges, CGNAT, VPNs, or whether the number stays the same over weeks. Those topics have their own posts.
What you are looking for
Think of two layers:
- Local (private) address — what your router gives your phone or PC. Useful at home. Invisible to most websites.
- Public address — what a remote server records as the source of your visit.
System settings almost always show the local one. A “what is my IP” page shows the public one. Mixing them up is the most common mistake. If you need the vocabulary for that split, see public vs private IP. For finding the number itself, keep reading.
Method 1 — Use a web check (best for almost everyone)
- Open the FindMyIP homepage in a normal browser tab.
- Read the public IP shown for this visit.
- Optional: open IP Lookup if you want network context (ISP/org style fields) for that same address.
That is enough for most questions: “What address do sites see for me on this Wi‑Fi?” or “Did my address change after I switched networks?”
Tips that matter:
- Use the same device and network you care about. Phone on cellular is not the same as laptop on home Wi‑Fi.
- Turn a VPN off if you want your ISP path. Turn it on if you want the VPN exit. The homepage always reflects this request, not every app on the device.
- Prefer HTTPS. You are only reading an address, but a clear site reduces the chance of a lookalike page.
Copy the address into a note if you need it for support, a game allowlist, or a before/after test. Do not treat an old screenshot as still true tomorrow.
Method 2 — Check again on another path
Public IP is a property of the path, not of “you” as a person.
Useful comparisons:
| Path | What you learn |
|---|---|
| Home Wi‑Fi, VPN off | Usual home/ISP public address |
| Phone cellular | Carrier exit (often different) |
| Same Wi‑Fi, VPN on | VPN provider exit |
| Work or café Wi‑Fi | That network’s exit |
Open the homepage once on each path and write down the numbers. If they differ, you measured different exits. That is expected. It does not mean your computer is broken.
If you only care which company owns the range you land on, paste the address into ISP Lookup or read find the ISP for an IP address.
Method 3 — What your device settings are (and are not)
Windows, macOS, iOS, and Android all show network details. Those screens are useful for Wi‑Fi troubleshooting. They are a poor primary tool for “what is my public IP?”
Typical pattern:
- Wi‑Fi details show something like
192.168.1.42or10.0.0.15. - That is your LAN address.
- The public address is assigned further upstream (your router’s WAN side, or the ISP).
So: use settings to confirm you are online and which Wi‑Fi you joined. Use the homepage for the public number.
Router admin pages (192.168.1.1 and similar) sometimes show a WAN IP. That field can match the public address on a simple home setup. On many ISP plans it shows a private-looking or shared address instead, while websites still see a different public IP. When the router WAN field and FindMyIP disagree, trust the web check for “what sites see,” then read carrier-grade NAT and shared public IPs if inbound access is the real problem.
Method 4 — Quick command-line checks (optional)
If you already use a terminal, you can ask a public echo service. Examples people use:
curl https://api.ipify.orgcurl https://ifconfig.me/ip
Treat the result like any other web check: it shows the public address for that command’s path. A VPN in the terminal environment, a proxy, or a different network interface can change it.
For most readers, the homepage is clearer and needs no typing.
Common mix-ups
“Settings say 192.168… so that is my public IP.”
Usually false. That range is local. Confirm on the homepage.
“I need my public IP to see if someone is hacking me.”
Knowing the number does not prove compromise. It only tells you which address this path presents. For what that label can imply, see what your IP address reveals — after you have the current value.
“The number changed since yesterday — how do I find the ‘real’ one?”
There may not be a single permanent number. Many home plans are dynamic. Finding your IP means checking now. Stability over time is a different question: does your IP address change.
“VPN is on but the site still shows my home IP.”
Some apps or browsers may not use the tunnel (split tunneling, extension issues, or the VPN not covering that process). Toggle the VPN, refresh the homepage, and compare. Deeper VPN behavior: what a VPN changes on your IP.
“I found an IP in an email header / game log — is that mine?”
Not automatically. Paste that address into IP Lookup to see what network it belongs to. Finding your public IP still starts from a check on your own connection.
A short checklist
- Open What Is My IP on the network path you care about.
- Note IPv4 and, if shown, IPv6 — they are different families; you may have one, the other, or both.
- If you need the ISP/org for that address, use ISP Lookup.
- If the number looks “wrong,” change one thing at a time (VPN off/on, Wi‑Fi vs cellular) and check again.
- Do not confuse the LAN address in system settings with the public address.
Bottom line
To find your public IP, ask a remote service what it sees. The FindMyIP homepage is built for that. Device settings show the local address. Router WAN fields can help on simple setups but can also disagree under shared ISP addressing. Check the path you actually use, save the number only when you need it for a task, and re-check when the network path changes.
