The IPv6 Link-local address is derived form the MAC- or Ethernet hardware address in the following way;
| Mac address: | XX:XX:XX:XX:XX:XX |
| IPv6 Link local address: | fe80::xyxx:xxff:fexx:xxxx |
Where y = X XOR 2. Furthermore ‘ff:fe’ is inserted and ‘fe80::’ prepended.
‘y = X XOR 2’ means inverting the 2nd bit from the right; Continue reading »
