Answer

It differentiates the modified address from the original MAC address. Explanation 1. Understand the 7th Bit in MAC Address The 7th bit of the first octet in a MAC address is known as the "Universal/Local" (U/L) bit. Flipping this bit changes the address from universally administered to locally administered or vice versa. 2. Determine the Effect of Flipping the 7th Bit Flipping the U/L bit differentiates the modified address from the original MAC address, indicating that it is now locally administered.
