Just for your information, current cvs version of ipv6calc now detects
such adddress as "link-local-teredo"

@Miguel: do you know which client uses such addresses?

@Pekka: can you check whether your examples with masked IIDs have some
correlation which can be used also for detection or are this original
link-local addresses? At least, the IIDs are from type "local".
