What were the differences between the IPv4 DHCP messages and the DHCPv6 messages?
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 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 is IPv6 Rdnss?
Recursive DNS Server Option The RDNSS option contains one or more IPv6 addresses of RDNSSes. All of the addresses share the same Lifetime value. If it is desirable to have different Lifetime values, multiple RDNSS options can be used.
How does Slaac differ from 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.
What are the differences 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.
When should I use DHCPv6?
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.
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.
What does Rdnss stand for?
In addition, four new terms are defined below: o Recursive DNS Server (RDNSS): Server that provides a recursive DNS resolution service for translating domain names into IP addresses as defined in [RFC1034] and [RFC1035].
What is RA based DNS config?
RA-based DNS configuration enables the full configuration of basic networking information for hosts without requiring DHCPv6. An IPv6 host can acquire the DNS configuration (that is, the DNS recursive server addresses and DNS Search List) for the links to which the host is connected.
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.
