Final answer:
The claim that DHCPv6 servers only hand out prefixes to DUIDs and not addresses is false. DHCPv6 is capable of assigning both prefixes for delegation and individual IP addresses to clients identified by their DUIDs.
Step-by-step explanation:
The statement that DHCPv6 servers hand out prefixes to DUIDs, and they don't hand out addresses is false. DHCPv6, the Dynamic Host Configuration Protocol for IPv6, is responsible for assigning not only prefixes but also full IPv6 addresses to clients in a network. Each client in DHCPv6 is identified by a unique DUID (Device Unique Identifier). The server uses this DUID to manage assignments to the client, which can include both individual addresses and prefixes.
When a DHCPv6 server assigns a prefix, it is generally providing a block of addresses that the client can then use to allocate to its own internal network devices. This process is known as prefix delegation. However, DHCPv6 is also able to assign individual IPv6 addresses to devices in a manner similar to DHCPv4. This capability is particularly important in scenarios where individual devices need to be reachable via a specific IP address or when stateful address configuration is desired.
