I don't know if this text is going into draft 20, but I have a nit.

Having extra data initialized to zero doesn't make sense.
How about instead saying 
	A sender MUST only send a packet with a length
	that is indicated by the No of Addrs field, and that a receiver MUST 
	ignore anything beyond the part of the packet indicated by
	the No of Addrs field. (This allows for future extensibility using
	the reserved field to indicate that there is some new information
	past the part of the packet indicated by the No of Addrs field.)
