When using the link local addresses, you have to specify the interface.
How? etho http://[fe80::8cae:84ff:fe43:27d4]/ invalid. http://[fe80::8cae:84ff:fe43:27d4]/ eth0 gets info on getting new tab. (about:newtab) etho http://[fe80::8cae:84ff:fe43:27d4]/ not understood. So? How do I type that into firefox or chrome? What's the syntax for specifying the interface? :-?
Also, that address contains a modified version (fffe added to the middle and bit 7 inverted, IIRC) of the device MAC address. You could check the MAC addresses of the various devices. You might also check your arp cache, to see if there's an IPv4 address that corresponds to the MAC address.
