What Is My Public IP?
Detect the public IP your traffic exits through, plus basic network geolocation.
By Aryan Khan, Founder & Editor · Updated October 2026
For example, the address shown is the one every website you visit already sees — which is why checking it with a VPN on and off is the quickest privacy sanity check there is.
How to use What Is My Public IP?
Use the detection button to check the address seen by the lookup provider:
Choose Detect my public IP to ask the lookup provider which public address your connection uses for that request. The result can include approximate network and location details; it does not identify a precise physical address.
- 1Select Detect my public IP.
- 2Read the returned IP, ISP and approximate location if available.
What people use What Is My Public IP? for
1. VPN sanity checks
Compare the reported address with your VPN enabled and disabled. A difference can be useful context, but an IP lookup alone cannot prove that all traffic or DNS requests use the VPN. For a specific address, use the IP Address Lookup.
2. Remote-access setup
Whitelisting your home or office connection for a server starts with this number — and the knowledge that it may change when your ISP reassigns it.
3. Support calls
“What IP are you coming from?” is support's way of finding your session in their logs. This page is the answer, ready to read aloud.
4. Understanding shared addresses
Offices, schools and carrier networks put many people behind one public address (NAT) — the page showing the same number on every desk is the architecture working, not a fault.
Worked examples
Run the lookup once with the VPN enabled and again with it disabled. Compare the reported addresses and network information. This checks only the connection to the lookup provider; it is not a complete VPN leak test.
Most home connections hold dynamic addresses that rotate on reconnects or lease cycles. Yesterday's address being different is your ISP's normal housekeeping, not an intruder — security alerts live elsewhere.
Your public IP, decoded
What the displayed address is made of.
| Aspect | Reality |
|---|---|
| Whose address it is | Your network's exit point — router, carrier gateway or VPN server |
| What sites learn from it | Network owner, rough geography, address family (IPv4/IPv6) |
| What it never carries | Your name, account or street address |
| How stable it is | Often sticky for months at home; changes on VPN, network or ISP reassignment |
| How many exist | IPv4: 4,294,967,296 total — the scarcity that NAT and IPv6 answer |
The result reflects the connection to the IP lookup provider. A different network, VPN route or address family may produce a different address.
Your public IP is the internet-facing address seen by external services
The public IP shown by this tool is the address through which your current traffic reaches the internet. On home networks it is usually assigned to the router or ISP connection rather than to one specific device.
A VPN, proxy, mobile carrier or corporate network can change the visible public IP. The associated location is therefore approximate network context and should not be treated as your physical location.
How to interpret the result
The most common errors come from using a correct result to answer the wrong geographic question. Keep these points in mind for What Is My Public IP?:
- IP assignments and geolocation databases change. Record the lookup time and source when network location is used for analysis or troubleshooting.
- Treat IP geolocation as an estimate of the network, not a precise physical address. VPNs, mobile carriers, proxies and corporate gateways can place an IP far from the actual device.
Limits & appropriate use
IP geolocation and network lookups have a hard competence boundary: they describe the network attachment, not the person or the precise street. City and region fields are database estimates that degrade under VPN, mobile, CGNAT and anycast. Treating an IP city pin as a GPS fix is the most common misuse.
Within that boundary the tools are useful for triage, localisation and rough audience analysis when the limitations are stated. Escalation for high-stakes identity or location claims is always offline verification, legal process or device-level consent — never an IP database alone.
- Legal or identity claims → due process and offline verification, not IP databases.
- Precise user location → browser GPS with consent, never IP alone.
- Abuse at scale → multiple telemetry sources and your own threat intel.
Data & methodology
When you select Detect my public IP, the browser requests the IP and available network metadata from ipwho.is. The result reflects the connection to that provider and may differ across networks, address families or VPN routes; geographic fields are approximate.

Key terms worth knowing
- Carrier-grade NAT
- A network setup where many customer devices share public IPv4 addresses.
- Public IP
- An Internet-routable address visible to external services.
Editorial guidance: MapBench explains the method and limitations so the tool can be used as a transparent reference, not as a black-box answer. For legal boundaries, safety-critical routing, surveying, engineering, regulated decisions or official statistics, verify the result with the responsible authority or a qualified professional.

Method, assumptions & limits
- This tool’s method
- When you select Detect my public IP, the browser requests the IP and available network metadata from ipwho.is. The result reflects the connection to that provider and may differ across networks, address families or VPN routes; geographic fields are approximate.
- Before relying on the answer
- Check which IP address was queried and whether a proxy, VPN or mobile network is involved. Network registration and device position are not the same thing.
- What the result cannot establish
- IP geolocation is approximate and may identify a provider's infrastructure. It cannot establish a person's precise location.
Coverage: Worldwide. Search, basemap and external data requests may use third-party services; browser-based does not mean every operation is offline.

Frequently asked questions
Clear answers about the calculation, accuracy and appropriate use.
VPN?
Shows the exit IP of the VPN or proxy, not your physical street address.
Is IP location the same as my physical GPS location?
No. IP geolocation estimates the network exit location and can be affected by VPNs, mobile carriers, proxies and ISP routing.
Can an IP lookup identify a street address?
No. Public IP geolocation is approximate and should not be treated as a precise home or device location.
Why does a VPN change the result?
A VPN routes traffic through another server, so public services usually see the VPN exit IP rather than your normal network address.
Is my public IP the same as my device's IP?
No — your device usually holds a private address (192.168…) inside your network; the router translates it to the one public address this page shows. The distinction is NAT, and it is why the whole street can share one public number.
Can someone find my home from this address?
Not from the address alone: public data resolves it to a network and an approximate area. Precise subscriber details sit with the ISP, released under legal process — the honest boundary, again.
Why does the page show IPv6 sometimes?
If your connection supports IPv4 and IPv6, the address shown depends on the connection used to reach the lookup provider. A single result does not test both address families.
My IP says a different city than mine.
Carrier and ISP routing centres concentrate addresses in hub cities. The shown geography is your network's, and for mobile connections it can sit a state away without anything being wrong.
Should I hide my IP?
A VPN shifts what sites see to the VPN's exit — a legitimate privacy tool with real trade-offs (speed, trust moved to the provider). This page is the measuring instrument either way: it shows what the world sees, so you can verify the choice works.
What is a static IP, and do I need one?
A fixed address that never rotates — sold by ISPs for servers and remote access. Most households neither have nor need one; dynamic addresses changing is normal, documented above.
Does the address reveal my browsing?
No — the address identifies a connection point, not activity. What you did on a site is that site's logs' business; the IP is merely the return address on the envelope.
The number changed mid-day.
IP addresses can change for several reasons, including switching networks, VPN routes, or ISP reassignment. A change alone does not establish whether a VPN is leaking.
