IP address lookup

Type any IP address and see where it is registered, who owns it and what kind of network it is. Your own address is filled in to start.

Press Look up for your own address, or paste another one.

Where the address block is registered, roughly. A city or two off is normal.

Anyone can look you up too

With Teal VPN, websites look up a Teal server instead of you.

Your provider, your city and your network type all change to the server’s. Free with 500 MB every day, no card.

What an IP lookup can and cannot tell you

Where the data comes from

Every block of addresses is registered to a company in one of five regional registries (ARIN, RIPE, APNIC, LACNIC, AFRINIC). That public record gives the owner and its network number. The city comes from location databases that map each block to where the owner uses it, learned from routing and from the owner’s own notes.

This page reads a monthly copy of that data on Teal’s own server. Nothing you type leaves it, and nothing is kept.

What it tells you

The country is reliable. The region and city are the provider’s best-known place for that block, often right, sometimes a hub city away. The owner tells you whether an address is a home provider, a mobile carrier, a university, a company or a hosting firm, which is the most useful line when you are checking where a visitor, a login or an email really came from.

A reverse name, when the owner has set one, often repeats the story: a home line, a mobile gateway or a server in a data centre.

What it cannot tell you

No lookup gives a person’s name, street address, phone number or exact position. Only the provider knows which customer used an address at a given minute, and it releases that only to a court. Sites that promise more are guessing or selling data they should not have.

If you want your own address to say less, connect through Teal VPN: every site then sees the Teal server’s registration instead of yours.

Questions

What can an IP address lookup tell me?

The country, region and city where the address block is registered, the company that owns the block (an internet provider, a mobile carrier or a hosting company), its network number (ASN), and sometimes a reverse name. It cannot tell you a person’s name, street or phone number.

How accurate is the location?

Country is right almost always. City is where the provider registered the block, which can be its hub rather than the user’s town, and mobile networks are often shown in another city. Treat the pin as “roughly here”, not an address.

Can I find out who is behind an IP address?

Not from a lookup. Only the provider knows which customer used an address at a given time, and it releases that only to a court order. A lookup shows the provider, and that is as far as public data goes.

What does “hosting” mean in the result?

The block belongs to a data-centre or cloud company rather than a home or mobile provider. Traffic from such an address usually comes from a server, a VPN or a proxy, not from a person’s home connection.

Why is my own address shown in another city?

Your provider registered the block somewhere else, or you are on mobile data, which is routed through a few central points. It is not a sign that anything is wrong.

How do I stop websites from looking me up?

Connect through a VPN. Websites then see the VPN server’s address and its registration, not your provider and city. Teal VPN does this with one tap and has a free plan with 500 MB every day.
