ランダムIPv6 ULAアドレスを生成

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.

ULA #1

/48 Prefix

fd9c:4be4:77a500::/48

Example subnet addresses:

fd9c:4be4:77a500:0001::1/128

fd9c:4be4:77a500:0002::1/128

Address Breakdown

Prefix bytefd (0xFD — locally assigned ULA)

Global ID (40-bit random)9c4be477a5

Subnet ID0000–FFFF (16-bit, assign per subnet)

Interface ID64-bit (assign per host)

ULA #2

/48 Prefix

fd90:3f36:a61000::/48

Example subnet addresses:
