Who is behind an IP address?
The top of the page shows your public IP address — the one websites see when you visit — along with its approximate city, region and time zone. Enter any IPv4 or IPv6 address or domain name to look it up: its approximate location, reverse DNS name and, from the official regional internet registry, the organization that owns it, its network range and the abuse contact for reporting spam or attacks.
Ownership details come from RDAP, the modern replacement for WHOIS run by ARIN, RIPE, APNIC, LACNIC and AFRINIC. Location is estimated from IP geolocation data and is usually accurate to the city or region — an IP address never reveals a street address.
