IP Address Lookup

See your public IP address, its location and network, or look up any IPv4 or IPv6 address or domain name.

IPv4, IPv6 or a domain name. Leave it empty to see your own IP.

What this IP lookup shows

Open the page and it shows the public IP address your browser connects from, with its country, region, city, postal code, time zone and coordinates, and, where the data has them, its network: the ISP or organisation the address is registered to, its ASN and the block it belongs to. Type any public IPv4 or IPv6 address, or a domain name, to look that up instead.

For your own address, we use the location our hosting edge attaches to your request when it includes a city, and fetch the ISP and ASN when you ask for them. Otherwise, and for every address you type, our server asks a third-party IP geolocation service (ipapi.co). A domain name is resolved with a DNS lookup and its first address is shown; we never connect to the site. The hostname is the address's reverse DNS record, also read through DNS.

Results are cached for up to a day, keyed by the address looked up, so repeat lookups don't go to the service again. Each visitor can run 20 lookups a minute.

What an IP lookup can and can't tell you

An IP address points to a network, not a person. A lookup tells you roughly where the address is used, which ISP, mobile carrier or hosting company it belongs to, and whether it has a reverse DNS name. That's enough to tell a home broadband address from a cloud server, or to confirm which country a proxy exits in.

It can't tell you who is using the address, their street address or what they do online. Only the ISP can match an address to a customer, and that information isn't in any public lookup.

How accurate is IP geolocation?

Country is usually right. City is an estimate: databases infer it from how address blocks are registered and routed, so a mobile or home address can show a nearby city, the ISP's regional hub or the capital. Treat the coordinates as the centre of an area, not a street address, and the OpenStreetMap link as a rough pin.

Mobile carriers send many customers through a few gateways, so mobile addresses are often placed far from the phone. Address blocks also change hands, and a block moved to another region can show its old location until the databases catch up. Different databases often disagree on the city, so a website can place you somewhere other than this page does.

How a proxy changes what websites see

Through a proxy, websites see the proxy's exit IP instead of yours, so a lookup shows the exit's location and network. Residential and mobile exits belong to home ISPs and mobile carriers; datacenter exits belong to hosting companies, and the organisation name usually makes that clear.

The IP is only part of what a site sees. Your browser still reports its own time zone and languages, and WebRTC can reveal another address unless it's turned off or routed through the proxy. The WebRTC leak test and the browser fingerprint test show whether those match the proxy location, and the HTTP headers checker shows what your client sends.

Using it to check a proxy

Send one request through your proxy to any "what is my IP" endpoint, copy the address it reports, and paste it here. If the country and network match what you asked for (for example, a German residential ISP for a line targeted at DE), the targeting is working. Run it on a few lines: rotating proxies should give you a different address on each request, sticky sessions the same address until the session ends.

BuyProxy's Core Residential lines target by country. Premium Residential adds state, city and ASN targeting, and sticky sessions from 3 minutes to 24 hours.

Questions

What is my IP address?

It's the public address your internet connection uses to reach websites, shown at the top of this page. At home it usually belongs to your router and is shared by every device on your network. On a phone it often comes from your mobile carrier and can be shared with many other customers.

Can someone find my exact location from my IP address?

No. A lookup gives an approximate area, usually the right country and a nearby city, plus the network the address belongs to. Your street address isn't part of IP geolocation data.

Why does my IP show the wrong city?

City-level geolocation is inferred from registration and routing data, so it often points to the ISP's nearest hub rather than where you are. Country and network are far more reliable.

Can I look up a domain name?

Yes. Type a domain such as example.com and we resolve it with a DNS lookup, then show the location and network of the first address it points to, with any other addresses listed. Our server never connects to the site itself.

Does this work for IPv6 addresses?

Yes. Paste a full IPv6 address and the same fields come back when the geolocation service has data for that block. If your connection uses IPv6, the page shows your IPv6 address.

Why does my IP address change?

Most home and mobile connections get a dynamic address that the ISP can reassign, for example when your router restarts. A proxy or VPN also changes the address websites see, and rotating proxies change it on every request or session.

Do you store the addresses I look up?

We cache each result for up to 24 hours, keyed by the address looked up and not by who asked, so repeat lookups are quick. To apply the rate limit, we count each visitor's lookups for one minute.
