What is IPv6 stateful?

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 is IPv6 stateless?

Stateless address autoconfiguration is the process that IPv6 nodes (hosts or routers) use to automatically configure IPv6 addresses for interfaces. If a node determines that its tentative IPv6 address is not unique, then autoconfiguration stops and manual configuration of the interface is required.

What is the difference between DHCPv4 and DHCPv6?

DHCPv4 – The administrator enables DHCP for each interface. Administration is on a per-logical interface basis. DHCPv6 – Explicit configuration is not necessary. This protocol is enabled on a given physical interface.

Why is it beneficial to use stateless DHCPv6?

Stateless DHCPv6 enables a device that has obtained an IPv6 address/prefix to get other configuration parameters from a DHCPv6 server.

What is stateful configuration?

In the stateful autoconfiguration model, hosts obtain interface addresses or configuration information and parameters from a server. The stateful autoconfiguration protocol allows hosts to obtain addresses and other configuration information from a server. …

What are the different types of IPv6 addresses?

The three types of IPv6 addresses are: unicast, anycast, and multicast.

• Unicast addresses identify a single interface.
• Anycast addresses identify a set of interfaces in such a way that a packet sent to an anycast address is delivered to a member of the set.

What is DHCP and DHCPv6?

The differences are that DHCPv6 uses Unique Identifiers, while DHCP uses MAC addresses to identify the client. DHCP messages are transmitted over IPv4 packets and DHCPv6 is transmitted over IPv6 packets. DHCPv6 uses Router Advertisement (RA) and IPv6 multicast messages and DHCP uses broadcast IPv4 messages on the LAN.

Should I use stateful or stateless IPv6?

The stateless approach is used when a site is not concerned with the exact addresses that hosts use. However, the addresses must be unique. The addresses must also be properly routable. The stateful approach is used when a site requires more precise control over exact address assignments.
