Matt,
The second excerpt says Link-Local addresses have the format fe80::/64,
the first excerpt says 1/1024 of the address space is available for
Link-Local addresses. To me this is a contradiction. It wouldn't have
been a contradiction if the second excerpt would mention something like
'Link-Local of type x'.
Anyway, I understand what is meant. Thanks,
dirk
