  1. Difference between locally and universally administered MAC address?

LAA has 2nd least significant bit in first octet set to 1, UAA has 0.

  1. What is the purpose of locally administered MAC address?

Some (few) users seem to need their own MAC addressing scheme. I don't think there's a specific application for LAA.

  • Thanks @Zaac67. Can't i set least significant bit in first octet to 0? – Henok Tesfaye Feb 7 at 11:29
  • Of course you can. The LSB set to 1 indicates a group address (broadcast or multicast); 0 is unicast. – Zac67 Feb 7 at 11:33
