Those coordinates are not your address. IP geolocation resolves to your provider's registered point of presence — the exchange or regional hub your traffic enters the internet through — which can sit tens or hundreds of kilometres away from you.

The AS number identifies the autonomous system that announces your address to the rest of the internet — in effect, which operator owns the route to you. It is the most stable identifier here: your IP may change, your AS rarely does.

A browser cannot see its own public address — only a remote host can report it back. This tool therefore queries ipwho.is and ipify.org directly from your browser for the address, location and routing data. Nothing is proxied through Zellio and no result is stored. The “This device” panel is computed locally and is not sent anywhere.

Frequently asked questions

What is a public IP address?

It is the address your internet provider assigns to your connection — the one websites and services see when you connect, as opposed to your private local network address (like 192.168.x.x on your home WiFi). Your public IP is unique across the entire internet (or at least your ISP's network) and is what websites log in their server access records. This is different from your device's local or private IP, which is only visible to devices on your immediate network and is reused across many networks globally. Understanding your public IP is useful for troubleshooting connectivity, configuring remote access, or checking if a VPN is active (your public IP will be different from your ISP's assigned address).

Does this show my exact location?

An IP can reveal an approximate region but not a precise address. The tool focuses on your IP and connection details, not personal location. IP geolocation databases can pinpoint your city or region with moderate accuracy (often within 10-50 miles), but they cannot determine your street address or specific building. This means websites can infer your country or city from your IP for localizing content, but they cannot identify exactly where in that city you are. For privacy-sensitive use cases, a VPN masks your real IP entirely by routing traffic through a VPN provider's address instead.

Why does my IP change?

Many providers rotate addresses periodically, and using a VPN or mobile network will show a different IP. Refresh to see the current one. Residential ISPs typically assign addresses via DHCP and may change your IP every few hours, days, or when your modem reconnects, while business connections often get static (unchanging) IPs. Switching networks (home WiFi to mobile data, for example) instantly changes your public IP to the new network's address. VPNs replace your real public IP with the VPN provider's address, so you'll see a different IP when connected to a VPN service.

Pro tips

Check this before and after connecting to a VPN. If the address is unchanged, the tunnel is not carrying your traffic.
Treat city-level geolocation as approximate. Being placed in the wrong city usually reflects a stale database rather than anything about your connection.
Latency matters more than bandwidth for calls and gaming — a fast connection with high latency still feels sluggish.
Re-test on the same network at different times before concluding a connection is slow; congestion varies through the day.
Remember there is a physical floor to latency: light in fibre covers about 200 km per millisecond, so distance sets a limit no upgrade beats.

About What Is My IP & Network Tester

Shows everything a site can work out about you the moment you connect: the address itself, where it geolocates to, which provider and autonomous system route to you, and how fast the link looks. It also flags the timezone mismatch that gives away a VPN, and separates what had to be looked up remotely from what was read locally on your device.

See your public IP address, basic connection profile and latency without installing anything. It is the quick way to confirm what address the internet sees you from, check whether a VPN is active, or sanity-check connectivity.

Lookups run from your own browser session, so you get an accurate view of your current network without third-party software. Refresh any time your connection changes.

A public IP address is what the internet routes replies to, so every site you visit necessarily sees it. What it reveals is narrower than people assume and wider than they would like: an internet provider and an approximate location, where city-level is often roughly right and street-level is not. Geolocation databases map ranges to places, and those mappings go stale, sometimes point at a provider's regional hub rather than the customer, and occasionally are simply wrong.

The address you see here usually is not permanent, and may not even be yours alone. Most residential connections receive a dynamic address that changes when the router reconnects or the provider's lease expires. Mobile and an increasing number of fixed connections sit behind carrier-grade NAT, where hundreds of subscribers share one public address — which is why an IP-based block sometimes catches people who did nothing, and why treating an address as identifying a person rather than a connection is a mistake.

Common use cases

Confirming a VPN or proxy is actually active before doing anything that depends on it.
Finding the address to give an administrator for a firewall or access allowlist.
Checking whether your provider has changed your address after a router restart.
Sanity-checking latency when a video call or game feels worse than usual.
Verifying what location a website is likely inferring about you.

How it compareswhatismyip.com and ipinfo.io return more detail about the address, including ASN and richer geolocation, from their own servers. The lookup here is deliberately minimal — the address and a latency reading — without building a profile of the visitor asking.
