Count: 3

IPv6 ULA (Unique Local Address) — RFC 4193. Range: fc00::/7. Locally assigned addresses use prefix fd00::/8 with a 40-bit random Global ID. Not routable on the public internet.

工具說明

Generate RFC 4193-compliant fd::/8 Unique Local Addresses for private IPv6 network planning. ULAs are guaranteed not to conflict with global unicast addresses.
