About this tool
IconVault's IPv6 ULA Generator creates random RFC 4193 unique local address prefixes for your private networks. Each prefix starts with fd (the fd00::/8 block), gets a random 40-bit global ID from your browser's secure random generator, and includes a random 16-bit subnet ID, formatted as a /64.
It is built for homelabbers, network engineers, and students who need private, non-routable IPv6 space that will not collide with anyone else's. Generate 1, 5, 10, or 20 prefixes at once and copy them all with one click. Free and runs fully in your browser.
