What is stateful and stateless?
Stateful services keep track of sessions or transactions and react differently to the same inputs based on that history. Stateless services rely on clients to maintain sessions and center around operations that manipulate resources, rather than the state.
Why is Slaac stateless?
Stateless DHCPv6 This time, the Router Advertisement has a flag called other-config set to 1. Once the client receives the message, it will still use SLAAC to craft its own IPv6 address. We call this approach stateless because the DHCPv6 server does not manage any lease for the clients.
Can a network use both Stateful and stateless IPv6?
Stateless autoconfiguration of IPv6 allows the client device to self configure it’s IPv6 addreess and routing based on the router advertisements. A network can use both stateful and stateless autoconfiguration at the same time, they are not mutually exclusive.
What’s the difference between stateless and DHCPv6 server?
Stateless configuration. Stateless works a bit different. The DHCPv6 server does not assign IPv6 addresses to the DHCPv6 clients, this is done through “autoconfiguration.”.
What is stateful autoconfiguration of IPv6 equivalent to?
Stateful autoconfiguration of IPv6 is the equivalent to the use of DHCP in IPv4. It requires a DHCPv6 service to provide the IPv6 address to the client device and that both client device and server maintain the “state” of that address (i.e. lease time, etc).
What’s the difference between a stateless and stateful address assignment?
A Stateful address assignment involves someone keeping track of the State. Which is to say, some system exists that provides a log that certain IP addresses were assigned to certain MAC addresses. DHCP / DHCPv6 keeps truck of such information. A Stateless address assignment does not keep track of what has or hasn’t been assigned.
