4. Dynamic DNS Update
Under the Intel ME Network Name Settings select Dynamic DNS Update and press <Enter>.
If Dynamic DNS Update is enabled then the firmware will actively try to register its IP addresses and FQDN in DNS using the
Dynamic DNS Update protocol. If DDNS Update is disabled then the firmware will not make an attempt to update DNS using
DHCP option 81 or Dynamic DNS update. If the DDNS Update state (Enabled or Disabled) is not configured by the user, then
the firmware will assume its old implementation where the firmware used DHCP option 81 for DNS registration but did not
directly update DNS using the DDNS update protocol. For selecting "Enabled" for Dynamic DNS Update, it is required that the
Host Name and Domain Name are set.
Option Description
Enabled The Dynamic DNS Update Client in FW is enabled.
Disabled The Dynamic DNS Update Client in FW is disabled.
