Re: A use for site local addresses?



Ok, rather than beat a dead horse, let me see if I understand.
The following prefixes are no longer going to be valid as there will not be
any local addresses
Prefixes:
         FE8, FE9, FEA, and FEB are Link local addresses
         FEC0 is the prefix of a site local address. Site local addresses
are the equivalent of a private IPv4 address.
         FF02::1 is address that multicasts to all nodes on the LAN.
         FF02::2 is address that multicasts to all routers on the LAN.

Multicast Prefixes:
         ffx1 : node-local, packets never lead the node
         ffx2 : link-local, packets are never forwarded by routers (they
stay on the link).
         ffx5 : site-local, packets never leave the site.
         ffx8 : org-local, packets never leave the organization. This are
handled by routing protocols.
         ffxe : global scope
