Reserved IPv6 Interface Identifiers

Registration Procedure(s)
Standards Action
Reference
[RFC5453][RFC7136]
Note
Full deployment of a new reserved IID value would require updates to 
IID generation code in every deployed IPv6 stack, so the technical 
justification for such a Standards Action would need to be extremely 
strong.
