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

Explanation:
DHCPv6 uses a pair of UDP ports to separate the client and server roles. The client uses UDP port 546 as its source port when it sends requests to the DHCPv6 server, and the server listens on UDP port 547. Replies from the server come from port 547 back to the client’s port 546. So, the port associated with the DHCPv6 client is 546. The port 547 belongs to the server side, not the client. The other numbers (68 and 67) are the DHCPv4 ports, not used by DHCPv6.
