The portion before the '%' is a plain old (link local) = ipv6 address. The
part after the '%' is a zone id. It's safe to ignore.

Because link local addresses share prefixes, they may need to be told
what interface to come out of. They can be ignored safely enough, or if
you want you use an arbitrary string like 'fe80::%/net.alt' as the = zone.
