IPv6 addressing architecture (2)

Link-local: fe80::/10
Addresses used for address resolution and bootstrap
Unique only on single link

Multicast: ff00::/8
Multicast addresses are scoepd as well
IPv4 - controlled by TTL, a whole mess
ff02::/16 - link, ff05:: - site

Global: the rest of the address
Similar to IPv4 global address, worldwide uniqueness
