Interface Identifiers in IPv6 unicast addresses are used
to identify interfaces on a link. They are required to be
unique within a subnet. Several RFCs have specified
interface identifiers or identifier ranges that have a
special meaning attached to them. An IPv6 node
autoconfiguring an interface identifier in these ranges
will encounter unexpected consequences. Since there is no
centralized repository for such reserved identifiers, this
document aims to create one.

RFC Editor Note
Make this change in Appendix A:
The following RFCs that generate interface identifiers need to be
updated if they wish to avoid conflicts with the reserved interface
Implementations of the following RFCs need to be aware of the
reserved interface identifier ranges when they allocate new
addresses. Future revisions of these RFCs should ensure that
this is either already sufficiently clear or that the text
is amended to take this into account.
