An IP address lookup tells you who and where an IP address belongs to. Paste any public IPv4 or IPv6 address and this tool returns its approximate geolocation (city, region, country), the ISP or hosting provider, the ASN (autonomous system number), the reverse DNS (PTR) hostname, and the timezone — plus format details like the decimal, hexadecimal, and binary representation of an IPv4 address. It is the fast way to identify where traffic in your server logs is coming from, to check whether an address belongs to a data centre or a residential ISP, or to confirm the location a VPN is presenting. Geolocation is derived from public IP databases, so it is accurate to the city or ISP level rather than a street address, which is exactly what network diagnostics and abuse triage need. Enter your own address or any address you are investigating; the lookup runs on demand and nothing you enter is stored.
Look up geolocation, ISP, ASN, reverse DNS, and IP format details for any public IPv4 or IPv6 address.
Geolocation data is provided by a third-party API. Private, reserved, and internal addresses are blocked.
