Residential or datacenter IP checker

Enter an IP address to see whether it sits in a published datacenter or VPN range, and which network announces it. To check a proxy, connect through it and press Check my IP.

Enter an address or press Check my IP.

What the three results mean

Datacenter or VPN: The address is in a range announced by a network that hosts servers: cloud providers, hosting companies and VPN services. Sites that score visitors by IP type count it as a datacenter address.
Known VPN: The address is in a range that a VPN provider is known to use. This result comes first when an address is on both lists.
Not in a datacenter or VPN range: The address is on neither list. Most such addresses are home broadband, mobile carriers and office connections. It is not proof of a residential address: content networks, universities and smaller hosts can be missing from the lists.

How the check works

The address is compared with two published lists of network ranges: one of datacenter and VPN networks together, one of VPN networks alone. The lists are built from the networks' ASNs, so a whole network is on a list or off it.
Your browser asks IPinfo which network announces the address, and GeoJS if IPinfo does not answer. That gives the network name, its ASN and the country.
Check my IP first asks ipify which public address your connection uses, then checks that address the same way. Through a proxy, that is the proxy's exit address.

The range lists on this page are a copy taken on November 14, 2026. Ranges that changed hands after that day are not in it.

What the checker cannot tell you

Home, mobile and business connections all give the same result. The lists hold datacenter and VPN networks only.
Whether an address on an internet provider's network is used as a proxy. A residential proxy exit reads as its provider's network, because that is the network it is on.
Whether a website will accept the address. Sites use their own databases, add reputation and behaviour to the IP type, and can disagree with these lists.
The exact city. The country comes from an IP location database and is an estimate.
Anything about a private or reserved address such as 192.168.1.10 or 10.0.0.5. Those are not on the public internet.

Why websites look at IP type

Ordinary visitors reach a website from a home, mobile or office connection. Servers and VPN services use ranges that hosting networks announce, and those ranges are published. A site that wants to limit automated traffic can therefore treat datacenter addresses differently: more challenges, lower limits or a block.

That is why the same request can load from a home connection and fail from a cloud server. For work that has to see a site as a local visitor does, such as ad verification, price checks and search result checks, the type of the exit address matters as much as its country.

Check the exit address of a proxy

Set the proxy in your browser, or in a browser profile that uses it.
Open this page through the proxy and press Check my IP. The address shown is the one websites see.
With a rotating proxy, press it again: each connection can exit through another address, and each is checked on its own.

To check many proxy endpoints at once, with their exit addresses and response times, use the proxy checker. To see what a browser still shows around a proxy, use the IP leak test. Proxy checker · IP leak test

IP type checker questions

How do I check if an IP is residential or datacenter?

Enter the address above. If it is in a published datacenter or VPN range, the result says so. If it is not, the network name shows who announces it: a home or mobile internet provider points to a residential or mobile address, a cloud or hosting company to a server.

Does "not in a datacenter or VPN range" mean the IP is residential?

Not on its own. It means the address is on neither list. Most such addresses belong to internet providers, but offices, universities, content networks and small hosts are there too. Read the network name before you call an address residential.

Why does another IP checker show a different type?

Each service builds its own database. They differ on small hosting companies, on providers that sell both home internet and servers, and on ranges that were sold or leased recently. Websites use their own sources as well, so no checker can say what every site will decide.

Can this tool detect a residential proxy?

No. A residential proxy exits through an address on an internet provider's network, and the checker reports that network. It has no data about how an address is used.

Does it work with IPv6 addresses?

Yes. The lists hold IPv6 ranges for datacenter and VPN networks as well as IPv4 ranges, and the network lookup accepts both.

Is the address I check stored?

No. It is sent to TrueProxies in the body of the request, matched against the lists in memory and not logged or stored. Your browser also sends it to IPinfo or GeoJS for the network name, and those services have their own policies.
