Question

For the IPv6 addresses, what two ways can the host address be auto-generated?

a) Randomly and sequentially
b) Dynamically and statically
c) Manually and automatically
d) EUI-64 and privacy extensions

Answer 1

The host address in IPv6 can be auto-generated using EUI-64 and privacy extensions. The correct answer is d) EUI-64 and privacy extensions.

Step-by-step explanation:

The correct answer is d) EUI-64 and privacy extensions.

EUI-64 stands for Extended Unique Identifier-64 and is an addressing scheme used to automatically generate host identifiers in IPv6. It uses the MAC (Media Access Control) address of the network interface card to create a unique identifier.

Privacy extensions, on the other hand, are used to provide a level of anonymity and prevent tracking of IPv6 addresses. Hosts can generate temporary, randomly generated addresses in addition to the EUI-64-based address to enhance privacy and security.

For IPv6 addresses, the two ways that the host address can be auto-generated are EUI-64 and privacy extensions. EUI-64 is a method where the host's MAC address is used to create a unique 64-bit interface identifier, part of the 128-bit IPv6 address. Privacy extensions, on the other hand, are used to generate temporary addresses that change over time, enhancing the user's privacy on the internet.
