What Is an IP Address Lookup?
An IP address lookup (also called IP geolocation) is the process of finding the real-world location, internet service provider (ISP) and other details associated with an IP address. Every device connected to the internet has a unique IP address, and each address can be traced back to an approximate geographic region.
What Information Can You Get from an IP Lookup?
A comprehensive IP lookup tool reveals:
- Country, region and city — accurate to city level in 70-80% of cases
- ISP and organisation — the company that owns the IP block
- Hostname — the reverse DNS entry for the IP
- AS number and name — the autonomous system that routes the IP
- Timezone — the timezone of the IP's registered location
- VPN/Proxy detection — whether the IP belongs to a VPN, proxy, Tor exit node or datacentre
How Accurate Is IP Geolocation?
IP geolocation is accurate to the country level in approximately 99% of cases. City-level accuracy ranges from 70-80% depending on the ISP and country. There are several reasons why an IP might show an inaccurate location:
- ISPs register IP blocks in a central location rather than where they are actually used
- Mobile networks route traffic through regional gateways
- VPN users appear to be in the VPN server's location
Use Cases for IP Lookup
IP address lookups are used for a wide range of legitimate purposes including fraud prevention, content geolocation, cybersecurity investigation, spam filtering and network troubleshooting.
