Free Random IP Generator

A random IP address generator will create valid looking, random IP addresses, which can be used in your tests (automated or manual). If your test, or the website/mobile app you are testing, requires a valid IP address, you can use this tool to create dummy IPs.

The generator will generate a valid, public IP address. This IP address can be used in your automated or manual tests when required by the website or mobile app you are testing.

The IPv4 address is the original format of an IP address and is still used by over 90% of all internet appliances. It consists of a 32-bit binary number, separated by dots.

An IPv6 address is an 128-bit binary number, separated by colons. As it is 128 bit, the number of possibilities is exponentially bigger than the original IPv4 address.

This depends on the programming language you are using. An example on how to do this with Javascript or NodeJS can be found below.

const randomIp = Array(4).fill(0).map((_, i) => Math.floor(Math.random() * 255) + (i === 0 ? 1 : 0)).join('.');
