In IPv6, Link Local fe80::1:1 is like what IPv4 does when there isn't a DHCP server (it auto assigns an address from 169.254.0.0/16 ). The IPv6 RFC documents two ways to generate these link local address. The second method generates addresses that are not dependent on the MAC address. Unlike the IPv4 standard, the IPv6 standard requires that this address always exists, even when a "real" (read globally routable) IPv6 address exists.
