IP Lookup

Look up an IP address.

Resolve an IP or hostname, run reverse DNS, and see where it's located.

About IP lookup

This tool resolves a hostname to its IP address (or runs reverse DNS on an IP to find its hostname) and geolocates it to an approximate country, region and city using the MaxMind GeoLite2 database. Geolocation is approximate — it reflects where an IP block is registered, not the exact device.

Investigating a mail server you found with the MX Lookup? Paste its hostname here to see where it lives.
