EUI-64
EUI stands for Extended Unique Identifier
(Modified) EUI-64 is a method of converting a MAC address (48 bits) into a 64-bit interface identifier.
This interface identifier can then become the 'host portion' of a /64 IPv6 address.
How to convert the MAC address:
Divide the MAC address in half. 1234 5678 90AB -> 1234 56 | 78 90AB
Insert FFFE in the middle. 1234 56FF FE78 90AB
Invert the 7th bit. 1234 56FF FE78 90AB -> 1034 56FF FE78 90AB
