About IPTool

IPTool is a free web toolkit for network engineers, system administrators and developers. It provides tools for IP address lookup, domain analysis, subnet calculation, port scanning and dozens of other network-related tasks. The project has been running since 2018 and is actively maintained.

What we offer

Over 30 tools across several categories: network information (IP, domain, ASN, MAC lookup), connectivity checks (ping, port scanner, email verification), calculators (IPv4/IPv6 subnets, uptime, cron, chmod, hash, encryption), converters (units, numbers, colors, Punycode), and reference databases (router passwords, hardware pinouts). All tools work directly in the browser with no registration required.

Privacy

Most tools run entirely in your browser - your data never leaves the page. Server-side tools (IP lookup, ping, port check) process queries in real time and do not store them. We use basic analytics (Google Analytics) to understand traffic patterns but do not track individual users or sell data.

Technology

IPTool is built with Symfony and PHP, served over HTTPS, and available in three languages: Ukrainian, English and Polish. Client-side cryptographic operations use the Web Crypto API. The site is hosted in Europe.
