Destination Options and Hop-by-Hop Options

Registration Procedure(s)
IESG Approval, IETF Consensus or Standards Action
Reference
[RFC2460][RFC2780]
Note
From [RFC2460] IPv6 Option Types are 8-bit values, structured as 
three subfields, are defined in [RFC2460] section 4.2:

   Each distinct 8-bit Option Type identifies a different option, i.e., the
   high-order 3 bits are considered part of the option identification.
   However, it is recommended that Option Types be assigned with distinct
   values in the "rest" subfield, until and unless that 5-bit space becomes
   full.
