Which DUID type is a 128-bit Universally Unique Identifier?

Explanation:
DHCPv6 uses DUIDs to identify clients, and there are several formats for these identifiers. The format that uses a 128-bit Universally Unique Identifier is the DUID-UUID. A UUID is a 16-byte value designed to be globally unique, independent of hardware addresses or enterprise numbers, so this DUID type directly represents a standard UUID. Other DUID formats—such as those based on the link-layer address with a timestamp, or those including an enterprise number with an opaque value—have different structures and lengths, not a 128-bit UUID.
