+1 to David’s suggestion. I as well have never found this ambiguous but I do see why people might. IMNHO we dictate the service ports things are sent to (hence listen on) whereas what clients and servers use for source ports is open to implementation Rob Robert Nagy CEO/ Senior Dive Master DeepDive Networking, Inc C: 408.480.5133 www.deepdivenetworking.com Sent from my iPhone On Feb 29, 2024, at 8:24 AM, David Farmer <[email protected]> wrote: Would this text clarify things? Clients receive DHCP messages on UDP (destination) port 546. Servers and relay agents receive DHCP messages on UDP (destination) port 547. Clients, servers, and relay agents MAY send DHCP messages from any UDP (source) port they are allowed to use, including their designated destination ports. Nevertheless, regardless of the source port the client uses, the server or relay agent MUST send traffic to the designated destination port of the client. And vice versa, regardless of the source port used by the server or relay agent, the client MUST send traffic to the designated destination port of the server or relay agent.

It’s a lot more important to have the specification clear and unambiguous. I think it has been shown that it isn’t. Happy with whatever solution there is consensus for, but the ambiguity has to be resolved I think.
