POINT-TO-POINT PROTOCOL FIELD ASSIGNMENTS PPP DLL PROTOCOL NUMBERS The Point-to-Point Protocol (PPP) Data Link Layer [146,147,175] contains a 16 bit Protocol field to identify the the encapsulated protocol. The Protocol field is consistent with the ISO 3309 (HDLC) extension mechanism for Address fields. All Protocols MUST be assigned such that the least significant bit of the most significant octet equals "0", and the least significant bit of the least significant octet equals "1".

Protocol field values in the "0xxx" to "3xxx" range identify the network-layer protocol of specific datagrams, and values in the "8xxx" to "bxxx" range identify datagrams belonging to the associated Network Control Protocol (NCP), if any. Protocol field values in the "4xxx" to "7xxx" range are used for protocols with low volume traffic which have no associated NCP. Protocol field values in the "cxxx" to "exxx" range identify datagrams as Control Protocols (such as LCP).

See RFC 1700 for details on contacting the IEEE. Vendors that desire to use their IEEE 802 OUI for PPP Vendor Extensions should register their OUI with IANA. Vendors that do not otherwise need an IEEE assigned OUI can request a PPP specific OUI from IANA out of the 'CF0000' range, which has both the "locally-assigned" and "broadcast/multicast" bits set to one.
