EUI-64 IPv6: Why flip 7th bit of 1st byte - Cisco
1) halving the mac address of device (MAC address have 48 bits) 2) Add FFFE (16 bits); hence 48 bits + 16 bits = Prefix ID Interface. 3) Finally reverses the seventh bit of the MAC address and copies the result to the block of the prfix ID Interface. Regards.
