ok
giusto una notazione storica: ai tempi di 6bone 2001::/3 era considerato
il mondo IPv6 conosciuto e dunque era quello che si utilizzava per i filtri
oggi non e' piu' cosi'

ok

approfitto di questa prima risposta per dire che fe80::/10 e' un range
speciale che viene usato per numerare automaticamente le interfacce
degli host cosi' che possano comunicare fra loro all'interno dello
stesso dominio di broadcast

corrisponde al range IPv4 169.254/16 ex RFC 3927
