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.
What are the advantages of stateful DHCPv6?
With stateful DHCPv6 addresses are allocated in much the same way as with IPv4 DHCP. It is up to the DHCP server to hand out addresses (or not) as it sees fit and to keep track of which client has which address.
How can you differentiate between the different types of Slaac stateless stateful DHCPv6?
SLAAC automatically works with a router, while Stateless DHCPv6 gives addresses using SLAAC and extra information using DHCP. The only configuration where the server gives IPv6 addresses is the Stateful one.
Is DHCPv6 stateless?
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 the advantage of stateful DHCPv6 has over stateless DHCPv6?
In this context stateless means that no server keeps track of what addresses have been assigned by which hosts and what addresses are still available for an assignment. A stateful DHCPv6 server provides IPv6 addresses and “other information” to hosts. It also keeps track of the state of each assignment.
What is Prefix Delegation in IPv6?
Quick Definition: Prefix delegation, also known as PD, is one of the methods available in IPv6 for communicating information to a device about what networks are available for subnetting. Service providers can assign customers a prefix to be used on their own internal networks.
Why is DHCPv6 stateless?
Stateless DHCPv6 is used by nodes to obtain other information, such as a DNS server list and a domain name, that does not require the maintenance of any dynamic state for individual nodes. A node that uses stateless DHCPv6 must have obtained its IPv6 addresses through some other mechanism usually SLAAC.
What is IPv6 subnet prefix-length?
10.255. The prefix-length in IPv6 is the equivalent of the subnet mask in IPv4. However, rather than being expressed in four octets like it is in IPv4, it is expressed as an integer between 1 through 128.
What is enable prefix delegation?
The prefix delegation feature lets a DHCP server assign prefixes chosen from a global pool to DHCP clients. The DHCP client can then configure an IPv6 address on its LAN interface using the prefix it received.
What is IPv6 delegated prefix?
Are there any advantages in using stateless address autoconfiguration instead of DHCPv6?
Advantages of Stateless Auto Configuration Allows hot plugging of network devices – The network devices can be ‘hot-plugged’ to the Internet. Since the devices can configure their own IP addresses, there is no need for manual configuration of the network devices.
Why is Slaac and stateless DHCPv6 stateless?
Stateless address auto-configuration (SLAAC) is a feature that enables IPv6 nodes to auto-generate globally unique addresses (GUA) using Route Advertisements messages sent by a router attached to the local segment. However, SLAAC does not provide DNS and Domain name information.
What is IPv6 prefix?
prefix-id is what is added to the prefix you receive from the ISP in order to obtain a /64 subnet.
What is the prefix in IPv6?
The /prefix-length variable is a decimal value that indicates the number of contiguous, higher-order bits of the address that make up the network portion of the address. For example, 2001:DB8::/32 is an IPv6 address prefix, indicating that the first 32 bits make up the network portion of the address.
