IP Address Lookup
Quick Answer
An IP lookup takes an IPv4 address and returns its approximate location, ISP, and timezone using geolocation data from a third-party provider.
What Is IP Address Lookup?
IP Address Lookup is a free online network tools tool that find your public ip address, country, city, isp and location. An IP lookup reveals the geolocation and network information behind an IP address — the country, city, ISP, and approximate coordinates. Every device connected to the internet has a public IP (or shares one through a NAT), and those addresses are registered to blocks managed by internet registries (RIRs) that publish basic whois data. This tool takes an IPv4 address and returns its approximate location, the organisation that owns the block, and the timezone. Accuracy varies: city-level data is often correct, but exact street addresses and postcodes are not available through public IP geolocation alone. The information comes from a third-party API (the connection is labelled on the page), so unlike most tools on Testrefy, this one does make an external request. No IP address is stored after the lookup completes. Unlike many similar tools, it runs entirely in your browser — no data is sent to any server, no account is required, and there are no usage limits. Whether you are a developer, writer, SEO professional, or casual user, this tool provides instant, accurate results without friction.
