Yes, it is. Or you can set this address inside your local network.
A typical usecase of 6to4 for a LAN could be:
^
| a.b.c.d public address
+-----+
RA* | CPE |
| +-----+ 2002:a.b.c.d::eui/64
| |
V +-----------+-
| |
H1 Hn
(*) the CPE advertises the 2002:a.b.c.d::/64 prefix or any prefix within
2002:a.b.c.d::/48 to the hosts.

The link-local address cannot be used beyond one hop, then you need an
address with a global scope in order to access to the IPv6 Internet.
