Yes. The reason is this: " # Note that it is presently the policy of IANA to assign a single well-known # port number for both TCP and UDP; hence, most entries here have two entries # even if the protocol doesn't support UDP operations. " > new entries should be specific, and where we have knowledge of the > protocols we should remove silly old ones. BGP, Gopher, HTTP, POP, > and IMAP over UDP look like good candidates for example.. I am all in favor of cleaning this file and removing useless entries. But be careful, this is not a user-editable file anymore, so we need to take into account that some stuffs that may not appear obvious to us may still be needed by people. -- Antoine
