universal/local bit in the address and inserting the hexadecimal number FFFE
between the upper and lower three bytes of the of the MAC address.
For example, if a device had an EUI-48 address of 28-9F-18-1C-82-35, the
global/local bit must first be inverted to meet EUI-64 requirements (i.e., 1 for
globally defined addresses and 0 for locally defined addresses), changing 28
to 2A. Then the two bytes FFFE are inserted between the OUI (i.e., company
id) and the rest of the address, resulting in a modified EUI-64 interface
identifier of 2A-9F-18-FF-FE-1C-82-35.
• This host addressing method allows the same interface identifier to be used
on multiple IP interfaces of a single device, as long as those interfaces are
attached to different subnets.
Example
This example uses the general network prefix of 2001:0DB8:0:1::/64 used in an
earlier example, and specifies that the EUI-64 interface identifier be used in the
lower 64 bits of the address.
