Section 5.1 of [RFC4944] defines the dispatch header and types. The ESC type is defined to use additional dispatch octets in the 6LoWPAN header. RFC 6282 modifies the value of the ESC dispatch type and that value is recorded in IANA registry [IANA-6LoWPAN]. However, the octets and usage following the ESC dispatch type are not defined in either [RFC4944] or [RFC6282]. In recent years with 6LoWPAN deployments, implementations and standards organizations have started using the ESC extension octets. This highlights the need for an updated IANA registration policy.

       IPv6 over Low-Power Wireless Personal Area Network (6LoWPAN)                 ESC Dispatch Code Points and Guidelines


   RFC 4944 defines the ESC dispatch type to allow additional dispatch    octets in the 6LoWPAN header.  The value of the ESC dispatch type was    updated by RFC 6282; however, its usage was not defined in either RFC    6282 or RFC 4944.  This document updates RFC 4944 and RFC 6282 by    defining the ESC extension octet code points and listing registration    entries for known use cases at the time of writing of this document.
