Who says so? It's anycasted, and operators source from it after making
note of this in the proper routing registries. RIPE NCC would confirm that
AS12859 can source from 192.88.99.0/24, just like the other operators 
in RFC3068-MNT can. If anybody marks this prefix as a bogon and filters 
it, that's their absolute right as a network operator. Their customers 
might not appreciate it that much though, if they would like to use 6to4.

I didn't say, type, or even think this.
