In section 3.2.1.3, we read: : A host MUST silently discard an incoming datagram that is : not destined for the host. An incoming datagram is destined : for the host if the datagram's destination address field is: : : (1) (one of) the host's IP address(es); or : : (2) an IP broadcast address valid for the connected : network; or : : (3) the address for a multicast group of which the host is : a member on the incoming physical interface. And earlier, in section 1.3.2: : In this document, the words that are used to define the : significance of each particular requirement are capitalized. : : These words are: : : * "MUST" : This word or the adjective "REQUIRED" means that the item : is an absolute requirement of the specification.
