How IP Lookup Works

Every public IP address belongs to a block that a regional internet registry hands to a network: an internet provider, a mobile carrier, a university or a cloud company. That network announces the block to the rest of the internet under its AS number, and databases record where its addresses are used.

This tool checks the address against our own copy of DB-IP's database, so the IP you enter isn't sent to a third party. It also asks DNS for the address's reverse hostname, which often names the provider or server (for example dns.google for 8.8.8.8).

Why Look Up an IP Address?

  • Check where an email, login alert or website visitor came from.
  • See which company runs a server or DNS resolver.
  • Confirm your VPN works: your own IP should show the VPN's network, not your provider.
  • Spot whether an address is a home connection or a data center.

IP Lookup FAQs

Quick answers to common questions.

The network that owns the address (usually an internet provider, mobile carrier, company or cloud host), its AS number, the approximate city, region and country, the reverse DNS hostname if there is one, and whether it looks like a home connection or a server.
No. It shows the network and an approximate area. Only the provider that owns the address can match it to a customer, and it normally only does so for a court order or police request.
Country is right almost always, region usually, and city often but not always. Mobile and VPN addresses can show a city far from the real user, because the location comes from where the provider registers the address block.
An Autonomous System Number identifies a network on the internet, such as AS15169 for Google or AS7922 for Comcast. Every public IP address is announced by one of these networks, which is how lookups find the owner.
Yes. Enter any public IPv4 or IPv6 address. Private addresses such as 192.168.x.x only exist inside a local network, so there's nothing public to look up.
