Generate random IPv4 addresses (like 203.0.14.88) or full IPv6 addresses for test data, documentation examples, and mock logs. Make one or hundreds and export the set.
When you are testing a system that stores or displays IP addresses, you need plausible-looking values that are not tied to anyone. This tool produces random addresses in either version, ready to drop into test fixtures or example configs.
Because they are random, some may fall in reserved or private ranges; for public-facing documentation, sanity-check against reserved blocks if that matters to you.
Frequently asked questions
What's the difference between IPv4 and IPv6?
IPv4 uses four numbers up to 255 (like 192.0.2.5); IPv6 is far longer, written as eight groups of hex, and exists because the world ran short of IPv4 addresses.
Are these safe to use in examples?
They are random and meant for testing; for published docs you may prefer the official example ranges reserved for documentation.
