Is DHCPv6 a protocol for stateless IPv6 address autoconfiguration?
It is the IPv6 equivalent of the Dynamic Host Configuration Protocol for IPv4. DHCPv6 is defined by RFC 8415. IPv6 hosts may automatically generate IP addresses internally using stateless address autoconfiguration (SLAAC), or they may be assigned configuration data with DHCPv6.
What is the difference between stateful autoconfiguration and stateless autoconfiguration for 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.
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.
What type of IPv6 address configuration uses DHCPv6?
DHCPv6. This is a combination of IPv6 Stateless Address Autoconfiguration (RFC 4862) and Dynamic Host Control Protocol for IPv6 (RFC 3315). It is a counterpart to IPv6 Stateless Address Autoconfiguration, and can be used with or without IPv6 Stateless Address Autoconfiguration to obtain configuration parameters.
What is stateless and stateful DHCPv6?
Stateful vs 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.
What is the difference between stateful and stateless DHCPv6?
Stateful vs Stateless DHCPv6 A stateless DHCPv6 server does not provide IPv6 addresses at all. It only provides “other information” such as a DNS server list and a domain name. A stateful DHCPv6 server provides IPv6 addresses and “other information” to hosts. It also keeps track of the state of each assignment.
Why is DHCPv6 necessary?
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.
Should I turn on DHCPv6?
Best answer: IPv6 can potentially add support for more devices, better security, and more efficient connections. While some older software may not work as expected, most of your network should work fine with IPv6 enabled.
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.
Is there auto configuration in the IPv6 protocol?
IPv6 Autoconfiguration. During the design of IPv6, then codenamed ‘IPng’, the design of “autoconfiguration” for IP was refactored to support a more automated method by which hosts could join an IPv6 network. In the base IPv4 protocol there is no explicit support for autoconfiguration.
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
How does the IPv6 stateless autoconfiguration mechanism work?
The IPv6 stateless autoconfiguration mechanism requires no manual configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The stateless mechanism allows a host to generate its own addresses using a combination of locally available information and information advertised by routers.
