Is "IP Address" scoped? (section 1)

[mwelzl]

From the review by Éric Vyncke:

Also Section 1:

Is IP Address scoped ? E.g., fe80::1%eth0 Can it be unicast, anycast,
multicast ? Even if section 6.1 is about this issue, it may be worth already
telling the readers.

Every IPv6 address is scoped by RFC4007 / RFC4291, while scope is orthogonal to being unicast/anycast/multicast.
Which scope and whether it is unicast/multicast/anycast is defined in the ipv6-address-space IANA registry and the ipv6-anycast-addresses IANA registry

If the Scope is not Global, there might be a zone-id to select the zone (oo-programmers would call it instance) of the scope.

Does it really make sense to make a summary of the above in the API?
