Why is it beneficial to use stateless DHCPv6?
The stateless Dynamic Host Configuration Protocol for IPv6 (DHCPv6) feature allows DHCPv6 to be used for configuring a node with parameters that do not require a server to maintain any dynamic state for the node.
What is a stateful DHCP server?
Configuring a stateful DHCPv6 server is similar to configuring a stateless server. The most significant difference is that a stateful server also includes IPv6 addressing information similar to a DHCPv4 server.
What is stateless and stateful IP address?
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.
What is stateless DHCP IPv6?
A stateless DHCPv6 server provides only configuration information to hosts and does not perform any address assignment. Such a server is called “stateless” because it need not maintain any dynamic state for individual clients.
Should I use DHCPv6?
DHCPv6 servers that assign randomized interface identifiers to end-node devices aid in the protection of the network from attacker reconnaissance attempts. Therefore, organizations should use DHCPv6 servers that are capable of providing randomized interface identifiers to lease requests.
Which is better DHCPv6 or Slaac?
If you do not have any requirement to restrict the hosts that can attach to the network using IPv6, then SLAAC, combined with DNS advertisement in the RA, and possibly with DDNS (if needed), would be the right choice. However, if the environment must be more secure, then DHCPv6 is likely to be the better solution.
Should you use DHCPv6?
What is a stateless IP address?
The stateless mechanism enables a host to generate its own addresses. The stateless mechanism uses local information as well as non-local information that is advertised by routers to generate the addresses. Routers advertise prefixes that identify the subnet or subnets that are associated with a link.
What is stateful IP address?
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.
Does IPv6 require DHCP if so how is it different from DHCPv4?
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.
Does DHCPv6 provide default gateway?
DHCPv6 does not provide the address, subnet mask, and default gateway that DHCP for IPv4 does.
What is the purpose of Slaac and DHCPv6?
Deploying and configuring DHCP for IPv6 (DHCPv6) is one way to assign addresses on an IPv6-enabled network. Stateless Address Autoconfiguration (SLAAC) is another way to assign addresses on an IPv6-enabled network.
What is stateful and stateless DHCPv6?
We call this approach stateless because the DHCPv6 server does not manage any lease for the clients. Instead, it just gives extra information as needed. Stateful DHCPv6 is the exact porting of DHCP into the IPv6 world. With this approach, a DHCPv6 server handles leases and extra information, just like traditional IPv4 DHCP.
Does disabling stateless mode disable stateful mode in DHCP?
Since disabling stateless mode seems to imply that you enable stateful mode, many recommend that you re-install your DHCP server and make sure that your DHCP server is in stateful mode because only then will it issue IPv6 addresses to DHCPv6 clients. This claim is wrong.
What is the difference between stateful and stateless TCP session?
TCP session follow stateful protocol because both systems maintain information about the session itself during its life. Stateless Protocol does not require the server to retain the server information or session details. Stateful Protocol require server to save the status and session information.
What is the difference between stateful and stateless request?
Stateful request are always dependent on the server-side state. TCP session follow stateful protocol because both systems maintain information about the session itself during its life. Stateless Protocol does not require the server to retain the server information or session details.
