Re: Site Local Addressing?

Indeed, "site-local" which was defined as FEC0::/10 is deprecated.
Essentially there was a big argument over what defined a "site" as
well as concerns about overlapping private addressing space. The
replacement as Anthony mentioned is ULA and is in the range FC00::/7 ,
which actually falls into two subnets depending on what you want to
do: FC00::/8 and FD00::/8. With the FC00::/8 your 40-bit global ID
is supposed to be assigned to you by a registrar. With the FD00::/8
the same 40-bit global ID is instead pseudo-randomly generated by your
router. The whole point of this is to avoid overlapping of private
sites within your infrastructure
