IP location lookup: where is this address?
Enter any IP address to see the country and city it's linked to, the internet provider behind it and its network number (ASN). You'll also see whether it looks like a hosting, proxy or mobile address. The box starts with your own IP, so the first results you see are about you; leave it empty and press the button to come back to them.

What kind of address is it?
How the lookup works
IP addresses are handed out in blocks, and every block is run by someone: a home internet provider, a hosting company, a mobile network or a business. Companies such as MaxMind (with its GeoIP2 database), IP2Location, ipinfo and ip-api keep records of who runs each block and roughly where it's used. This tool asks one of them, ip-api, about the address you enter.
Here's what the results mean:
- Country / region / city - roughly where the address is used. The further down the list you go, the less exact it gets.
- ASN - short for autonomous system number, an ID for the network the address belongs to. For proxy users it's one of the most telling lines on the page.
- ISP / organisation - the company that runs the block.
- Datacenter, proxy and mobile flags - educated guesses about whether the address belongs to a data centre, a known anonymous proxy or a mobile network. Treat them as hints, not proof.
Why the network can matter more than the address
There are far too many addresses for websites to judge one at a time, so many of them judge whole networks (ASNs) instead. Amazon's cloud, AWS, runs the network AS16509. Once abuse has been reported from some of its addresses, the whole network tends to be marked as "data centre, treat with care". That's why an address from a cloud company can face extra checks on its very first visit.
Home and mobile networks work the other way round. Comcast (AS7922), AT&T (AS7018) and Vodafone UK (AS5378) serve ordinary households and phone users, so their addresses usually start out with a good name. That standing is a big part of what you get from residential and mobile proxies.
How accurate is the location?
- Country - 99%+ accurate. If it says "US", it's almost certainly the US.
- City - right roughly 50-80% of the time, depending on the database and the country. It can be hundreds of km out when a provider routes a whole region through one hub (known as a PoP, or point of presence).
- Postcode - often wrong, so treat it as a rough hint at best.
For most proxy uses, the country and the network are what count. Think of the city as a bonus.
Checking a proxy you've just bought
Got a new proxy? Look up its IP here before you rely on it, and check that:
- The country is the one you ordered.
- The network fits what you were promised. For a residential proxy, it should be a home internet provider.
- For residential, static ISP and mobile proxies, "Datacenter / hosting" says No.
- For a mobile proxy, "Mobile carrier" says Yes.
If something doesn't match, ask the seller about it, but remember these databases get things wrong too, especially cities. We expect our proxies to pass these checks, and we'd rather you tried them yourself than took our word for it.
