The answer is that fc00::/7 matches 2001:: better because it gets the same label (ipv6_saddr_label()). Although fc00::/7 addresses are defined as global unicast IMHO they should be treated *slightly* different. This is the patch. Since 6to4 has its own label I have decided to assign one to Teredo too. However, I still haven't found any clue in referneces to unassigned value of hiscore.addr_type. -- Było mi bardzo miło. Czwarta pospolita klęska, [...] >Łukasz< Już nie katolicka lecz złodziejska.
