About the Random IP Address Generator

IP addresses identify devices on a network. Random addresses are handy as placeholder or sample data when testing software, logs and documentation.

This tool generates random IPv4 or IPv6 addresses in bulk, right in your browser.

The addresses are random and may not be routable on the public internet, which is exactly what you want for tests.

Frequently asked questions

Are these real, routable IP addresses?
They are random and structurally valid, but they may fall in reserved or unassigned ranges and are not meant to be routable. They are intended as sample data.
What is the difference between IPv4 and IPv6?
IPv4 uses four numbers separated by dots (for example 192.0.2.1). IPv6 uses eight groups of hexadecimal separated by colons and provides a vastly larger address space.
Can I generate many at once?
Yes. Set the count and they are generated together for easy copying.
