What is the UDP port number used by the DHCPv6 server?

Explanation:
DHCPv6 uses UDP with distinct ports for the client and the server. The client uses UDP port 546, and the server listens on UDP port 547 to receive DHCPv6 messages. When the server replies, it uses port 547 as the source and sends to the client’s 546. So, the UDP port number the DHCPv6 server uses is 547. The other ports listed belong to DHCP for IPv4 (67 and 68) or are the client-side port, not the server port for DHCPv6.
