How do I get IPv6 Duid?
The DUID is stored on the firewall in /var/phion/preserve/boxnet/DHCPv6 in the file dhclient. leases , where stands for the number of the DHCP interface.
What is Duid in IPv6?
The DHCP unique identifier (DUID) is used by a client to get an IP address from a DHCPv6 server. It has a 2-byte DUID type field, and a variable-length identifier field up to 128 bytes. Its actual length depends on its type.
Is DHCPv6 the same as IPv6?
DHCPv6 performs the same role in IPv6 as DHCP does in IPv4. It allows a central server to distribute addresses and other configuration information to a number of hosts.
How many Duid can each DHCPv6 server have?
By using the entire 128 bits of the DUID space in DHCPv6, there are 2128, or 340 undecillion, possible DUIDs.
What is DHCPv6 IAID?
The Client ID in DHCPv6 consists of two parts: a DHCP Unique Identifier (DUID) and an Identity Association Identifier (IAID). The DUID identifies the client system (rather than just an interface, as in DHCPv4), and the IAID identifies the interface on that system.
What is a Duid number?
Each entity in a DHCP operation, the client and the server, has a DHCP unique identifier (DUID). DHCP clients use DUIDs to identify a server in messages where a server needs to be identified.

Should I use DHCP for IPv6?
When it comes time for your organization to start to implement IPv6 at your end-user LAN networks, then you should be using DHCPv6 on a legitimate DHCPv6 server. This change will also mean that your organization would want to have DHCP operate the same for both protocols.
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.
Why is DHCPv6 called 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.

How do I find my Duid and IAID?
You can find the DUID and IAID values for any Microsoft node with “ipconfig”, under DHCPv6 IAID and DHCPv6 Client DUID. These appear in ipconfig only if Managed Address is enabled (either from Router Advertisement M flag, or manual setting of Managed Address option with netsh or NetConf).
