Unique Local IPv6 Generator

This is a randomly generated 48-bit unique local IPv6 prefix as defined by RFC 4193. It can be used for local IPv6 networking. A new random prefix will be generated every time the regenerate button is pressed

fd5e0e:f5ae:3c::/48
First Subnet:
fd5e0e:f5ae:3c::0::/64
Last Subnet:
fd5e0e:f5ae:3c::ffff::/64

IPv6 Unique Local Addresses (ULAs) are used similarly to IPv4 private addresses, such as 10.0.0.0/8. Unlike their IPv4 counterparts, IPv6 ULAs have a 40-bit random part, which makes them unique. The goal of IPv6 ULAs is to minimize the risk of address conflicts when connecting private IPv6 networks together.

For more information, refer to RFC 4193.
