Random IP generator

Generate random IPv4 and IPv6 addresses for testing, labs, mock data and docs. Public IPv4 skips every private and reserved block. It all runs in your browser — nothing is sent anywhere.

What each type is good for

Public IPv4 — routable internet addresses with 10/8, 172.16/12, 192.168/16, 127/8, 169.254/16, 0/8, multicast (224/4) and reserved (240/4) excluded.
Private IPv4 — RFC 1918 space (10.x, 172.16–31.x, 192.168.x) for LAN labs and firewall-rule samples.
IPv6 — global-unicast addresses in the 2000::/3 range, fully hextet-formatted.

These are randomly generated for testing and documentation. A real, in-use address may land here by chance — don't treat any output as unassigned.

Random IPs are easy. Finding the wrong one on your network isn't.

A duplicate address, a stale lease or a device on the wrong subnet hides in plain sight. Acutis Go runs a 60-second check across your network, DNS and your own machine and tells you plainly where the fault is — no guessing. Free.
