IP Address Lookup
ServerLocate any IP — geo, ISP, ASN and reverse DNS.
How it works
Look up any IP address — not just your own — to find its approximate location, ISP, network (ASN) and reverse-DNS hostname. Useful for checking where a login, email, or server request came from.

IP geolocation is approximate — it identifies the ISP's region, not a precise street address.
About the IP Address Lookup
Every public IP address maps to a location, an internet provider and a network. This free IP address lookup tool finds the geolocation, ISP, ASN and reverse-DNS hostname of any IPv4 or IPv6 address — useful for investigating traffic, logins and abuse.
Enter any address to trace where it's from.
What an IP lookup reveals
- Approximate country, region and city.
- The internet provider (ISP) and organisation.
- The autonomous system number (ASN) that routes the address.
- The reverse-DNS (PTR) hostname, when one exists.
What you can learn from an IP
- Approximate location — country, region and often city.
- The internet provider (ISP) and organisation.
- The network (ASN) that routes the address.
- The reverse-DNS hostname, when one is set.
Frequently asked questions
What can I learn from an IP address?
An IP lookup shows the approximate location, the internet provider, the network (ASN) and often a reverse-DNS hostname — enough to understand where traffic originates.
How accurate is IP geolocation?
It's typically accurate to the country and often the city, but it reflects the network's registration, not a precise physical address.
Can I look up any IP?
Yes, any public IPv4 or IPv6 address. Private addresses used inside local networks can't be geolocated.
How accurate is IP geolocation?
It's typically accurate to the country and often the city, but it reflects where the network is registered, not a precise physical address. VPNs, mobile networks and corporate routing can place a user far from their real location.
