Free Online Random IP Generator

An IP builder outputs syntactically valid IPv4 (four octets) or IPv6 (eight hex groups) addresses, with optional RFC1918 filtering, via crypto.getRandomValues.

How to Use This Generator

  1. Pick a Version: IPv4 or IPv6.
  2. For IPv4, choose a Range: Any, Public (routable), or Private (RFC1918).
  3. Set Count (1–100) and click Generate.
  4. Click Copy all to copy the list.

What Is a Random IP Generator?

Backend engineers writing fixtures, network testers running load simulations and security researchers seeding mock data all need a steady stream of valid-looking IP addresses. This generator outputs IPv4 (four 0–255 octets) or IPv6 (eight 16-bit hex groups, full notation), drawn from crypto.getRandomValues for unbiased coverage.

IPv4 supports three modes. Any picks completely uniformly. Public skips every reserved block (0.0.0.0/8, 10/8, 127/8, 169.254/16, 172.16/12, 192.168/16, 224/4 and others) so the result is a plausible internet-routable address. Private draws only from the three RFC1918 blocks (10/8, 172.16/12, 192.168/16) for local-network fixtures.

Generate up to 100 per click and copy the lot into your fixture file or load-test config.

Frequently Asked Questions

Which IP ranges are supported?
Any, public-routable, or RFC1918 private (10/8, 172.16/12, 192.168/16) for IPv4. Plus full IPv6.
Are these real addresses?
They're syntactically valid but generated for testing. Don't probe them.
Is IPv6 supported?
Yes — full 128-bit IPv6 in standard colon-hex notation.
