Prefixing the IPv6 address with fe80: generally means it's an IPv4 > -> IPv6 address (IIRC). 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.)
