The concept of stateless configuration revolves around the fact that there is no central server required by the network configuration. It differs from DHCP as no central server is required, hence less hassle for configuring the server. The main advantages of stateless configuration are:-
No need to store any data such as lease assignments.
It starts with the link-local network.
Numerous addresses are available on the link-local network, a host can generate an address that is unlikely to be duplicated anywhere on the network.
The network prefix is fixed, hence the host can broadcast to the network, asking if any other host on the network is using the address.
Stateless configuration in IPv6 eliminates the need for a central server in network configuration, distinguishing it from DHCP. The key advantages include no need for storing lease assignments, initiation within the link-local network, the availability of numerous unique addresses, and a fixed network prefix allowing hosts to broadcast and check for address conflicts on the network.
