In order to publish that text we need to agree on what it means. Can you
explain the semantics of the the interface identifier of a manually
configured IPv6 address? What are they used for?

Note: the semantics are *not* the same as the prefix length of an IPv4
address. The prefix length of an IPv4 address implies that that subnet is
reachable on, but the IID implies nothing about reachability.
