DHCPv6 is the DHCP protocol for IPv6 networks.
DHCPv6 is the DHCP protocol for IPv6 networks. It is functionally similar to DHCP for IPv4, but there are some differences due to the differences between IPv4 and IPv6.
DHCPv6 is used to assign IPv6 addresses to clients, and to provide other configuration information to clients. It is used in the same way as DHCP for IPv4, but there are some differences due to the differences between IPv4 and IPv6.
One key difference between DHCPv4 and DHCPv6 is that DHCPv6 does not use broadcast messages. All communication between DHCP servers and clients is done using unicast messages. This is because IPv6 addresses are not easy to spoof, so there is no need for DHCP servers to use broadcast messages to find clients.
Another key difference is that DHCPv6 includes a feature called "prefix delegation". This allows DHCP servers to delegate a prefix of IPv6 addresses to clients, rather than assigning a single IPv6 address to each client. This makes it easier for clients to connect to multiple networks, because they can use the assigned prefix to create addresses on those networks.
