DHCPv6 is used in which IPv6 address autoconfiguration method?
Click on the arrows to vote for the correct answerA. B. C. D.
DHCPv6 (Dynamic Host Configuration Protocol version 6) is a protocol that enables automatic configuration of IPv6 addresses for devices on a network.
IPv6 autoconfiguration methods can be divided into two categories: stateful and stateless.
Stateless autoconfiguration: It is also known as SLAAC (Stateless Address Autoconfiguration). In this method, devices can automatically generate their IPv6 addresses without requiring a central server or DHCPv6. The device generates its IPv6 address based on its MAC address, also known as EUI-64 address generation. It uses the Neighbor Discovery Protocol (NDP) to obtain other network parameters such as the default gateway and DNS servers.
Stateful autoconfiguration: In this method, DHCPv6 is used to provide IPv6 addresses and other network parameters to the devices on the network. DHCPv6 assigns IPv6 addresses to the devices and also provides other parameters such as DNS servers, default gateway, and subnet mask.
Cryptographically Generated Addresses (CGA) is another IPv6 autoconfiguration method, but it is not related to DHCPv6. It is a method for generating IPv6 addresses based on a public key and digital signature.
So, coming back to the question, DHCPv6 is used in the stateful autoconfiguration method. Therefore, the correct answer is A. stateful autoconfiguration.
