Nope. That's a link-local address. Any NIC can configure itself with
and address using that prefix and a host part generated from the MAC
address completely automatically, and thus communicate on any locally
attached network. (See RFC 5156 for the gory details.)
IPv4 mapped addresses are like this:
::ffff:192.0.2.0
(or you can express the 32 bits of the IPv4 address as two
colon-separated hex strings in the usual IPv6 idiom.)
Cheers,
