About IPVoid
Free IP, DNS, networking, and security tools. Online since 2010, built by the team behind APIVoid and trusted by thousands of analysts every day.
IPVoid is a free service developed and maintained by NoVirusThanks. It was born in 2010 as an IP blacklist checker that scans an address through dozens of DNSBL and IP reputation services. At the end of 2016 we started adding more IP, DNS and network tools, and today the site hosts over 200 utilities for troubleshooting networks, investigating abuse and gathering information about IP addresses, domains and websites.
Every tool is free to use without registration. Some security tools like blacklist checks, whois, ping, traceroute, DNS, SSL and HTTP inspections run from our servers and through the APIVoid APIs. Text, encoding, hashing, file, extraction and random-data tools run entirely in your browser and show the "Runs in your browser" badge, so the data never leaves your device.

A fresh new look
In October 2026, we updated our website layout and added new security tools that our users had requested over the previous few months. The redesign was inspired by PlanetScale’s minimalist website. In 2025, PlanetScale redesigned its website to resemble a markdown file, and we loved the idea! We took inspiration from their design to refresh IPVoid’s look.
Fair use policy
Please do not run automated queries against IPVoid: our systems automatically rate-limit and may ban addresses that generate too many requests. If you need these checks in your own software or within your company, most of them are available as JSON APIs on APIVoid with a free 30-day trial.
Say hello 👋
Ideas, bug reports, sponsorship and partnership requests are welcome on the contact page. If IPVoid saves you time, sharing it with a colleague is the best way to support the project and keep it free.
