Question

What are the two methods a device can use to generate its own IPv6 interface ID?

A. SLAAC
B. Stateless DCHPv6
C. Stateful DCHPv6
D. EUI-64
E. Randomly generated

Answer 1

A device can use either SLAAC or randomly generated methods to generate its own IPv6 interface ID.

Step-by-step explanation:

There are two methods a device can use to generate its own IPv6 interface ID:

1. SLAAC (Stateless Address Autoconfiguration): In this method, a device uses the MAC address of its network adapter to create its unique interface ID. The MAC address is typically a 48-bit value that uniquely identifies a network adapter. The device takes this MAC address, inserts the hexadecimal value FFFE into the middle, and then flips the seventh bit (universal/local bit). This process generates an IPv6 interface ID.
2. Randomly generated: Some devices can use a random number generator to create a completely random IPv6 interface ID. This method ensures that the interface ID is not related to the MAC address or any other identifiable information.
