Should I use DHCPv6?
DHCPv6 provides more control to the administrator in assigning addresses. If you really want that sort of control over your IPv6 addresses, you don’t understand IPv6 yet. It also can be used to provide additional configuration parameters beyond the basic address/gateway supported through autoconfiguration.
What is autoconfiguration IPv6?
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.
Does IPv6 require DHCP if so how is it different from dhcpv4?
Both protocols provide DHCP options to the end node to provide additional information. DHCPv6 uses Router Advertisement (RA) and IPv6 multicast messages and DHCP uses broadcast IPv4 messages on the LAN. DHCP for IPv4 can provide the default gateway IP address to the client, whereas DHCPv6 does not have this option.
What is difference between 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.
Why is stateless DHCPv6 beneficial?
An advantage of DHCPv6 for dynamic address assignment is that it is capable of providing additional information to the nodes. DHCPv6 provides DNS information and uses a 16-bit option space. These options are useful for devices like IP phones.
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.
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.
How does IPv6 autoconfiguration work?
A host performs several steps to autoconfigure its interfaces in IPv6. The autoconfiguration process creates a link-local address. The autoconfiguration process verifies its uniqueness on a link. The process also determines which information should be autoconfigured, addresses, other information, or both.
When using DHCP for IPv6 ie DHCPv6 what port do clients receive responses on?

Can Slaac and DHCPv6 be used together?
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. You need to tune Neighbor Discovery flag with ipv6 nd other-config-flag and ipv6 nd managed-config-flag commands.
Is DHCPv6 stateful?
A stateful DHCPv6 server provides IPv6 addresses and “other information” to hosts. It also keeps track of the state of each assignment. It tracks the address pool availability and resolves duplicated address conflicts. It also logs every assignment and keeps track of the expiration times.
Should I use stateless or stateful IPv6?
Why do I need IPv6 instead of DHCPv6?
IPv6 and RFC 2462 provide a means for hosts to configure their own IP addresses via stateless address autoconfiguration. To me this seems like the bee’s knees, and it leaves me wondering why someone would want to go through the trouble of configuring a DHCPv6 server instead.
What are the new features of IPv6 autoconfiguration?
One of the new features of IPv6 is built in autoconfiguration. There are two basic approaches: Stateless via Route Advertising (routers multicast the routes and address ranges allowing devices chose their own address from the pool) and Stateful via DHCPv6 (the server manages the addresses and configuration).
Why do we use DHCPv6 instead of Autoconfig?
One thing that DHCPv6 supplies that autoconfig doesn’t is DNS servers. the network administrator should have control over who gets (which) IPv6 addresses, e.g. because they need to be in sync with AAAA DNS records, or
What is hierarchical dynamic host configuration protocol for IPv6?
Hierarchical Dynamic Host Configuration Protocol for IPv6 (DHCPv6) for stateless configuration parameters allows a stateless or stateful DHCPv6 client to export configuration parameters (DHCPv6 options) to a local DHCPv6 server pool. The local DHCPv6 server can then provide the imported configuration parameters to other DHCPv6 clients.
