IP2Location IP-ProxyType-Country-Region-City-ISP Database (PX4) is a downloadable database that identifies IP addresses used as VPN servers, open proxies, web proxies, Tor exit nodes, search engine robots, and data center ranges. The database provides geolocation information including country, region, city, and ISP details for each IP address range. The database is available in multiple formats including binary (BIN), CSV, and CIDR. It covers both IPv4 and IPv6 addresses with daily updates. The IPv4 database contains over 5.7 million rows in CSV format, while the IPv6 database contains over 6 million rows. The combined binary database is approximately 698 MB. The database categorizes proxy types into six classifications: VPN (Virtual Private Networks), TOR (Tor Exit Nodes), DCH (Hosting Provider/Data Center), PUB (Public Proxies), WEB (Web Proxies), and SES (Search Engine Robots). Each proxy type is assigned an anonymity level ranging from low to high. The product is delivered as a subscription-based database that can be downloaded and integrated into existing systems. It supports all server platforms and programming languages. Users can automate the download process using provided scripts. The database fields include IP address ranges (ip_from, ip_to), proxy type, country code, country name, region name, city name, and ISP information.
