Question

Which of the following enables automatic configuration of an IPv6 address?

a. EUI-64 (Extended Unique Identifier-64)
b. UEFI (Unified Extensible Firmware Interface)
c. APIPA (Automatic Private IP Addressing)
d. MAC-48 (Media Access Control-48)

Answer 1

EUI-64 (Extended Unique Identifier-64) is used to automatically configure IPv6 addresses by extending a device's MAC address to create a unique 64-bit identifier.

Step-by-step explanation:

The feature that enables automatic configuration of an IPv6 address is a. EUI-64 (Extended Unique Identifier-64). EUI-64 is a method used to create a unique 64-bit interface identifier for an IPv6 address based on a device's MAC address. This method extends the 48-bit MAC address to create a 64-bit address by inserting a fixed series of bits in the middle of the MAC address. It is a key part of the IPv6 protocol's ability to automatically configure itself without the need for manual IP address assignment or DHCP.
