1E6F:65FF:FEC2:BDF8 Explanation: To derive the EUI-64 interface ID by using the MAC address 1C-6F-65-C2-BD-F8, three steps are taken. Change the seventh bit of the MAC address from a binary 0 to a binary 1 which changes the hex C, into a hex E. Insert hex digits FFFE into the middle of the address. Rewrite the address in IPv6 format. The three steps, when complete, give the interface ID of 1E6F:65FF:FEC2:BDF8.
