The goal of this specification is to allow compatible and interoperable implementations for transmitting IP datagrams and ARP requests and replies. To achieve this it may be necessary in a few cases to limit the use that IP and ARP make of the capabilities of a particular IEEE 802 standard. This memo describes the use of IP and ARP on the three types of networks. At this time, it is not necessary that the use of IP and ARP be consistent across all three types of networks, only that it be consistent within each type. This may change in the future as new IEEE 802 standards are defined and the existing standards are revised allowing for interoperability at the Data Link Layer.
