# Defining IP and FQDN Settings

Each Intel AMT device can have its own IP and FQDN settings. The IP and FQDN settings are usually the same as those defined in the host operating system, but they can be different. Intel SCS puts these settings into the Intel AMT device.

To define the IP and FQDN settings:

1. From the FQDN section, select the source for the FQDN (hostname.suffix):
   - Use the following as the FQDN:
     - Primary DNS FQDN – The hostname part of the FQDN is the hostname from the host operating system. The suffix is the “Primary DNS Suffix” from the host operating system. This is the default setting and is correct for most network environments.
     - On-board LAN connection-specific DNS FQDN – The hostname part of the FQDN is the hostname from the host operating system. The suffix is the “Connection-specific DNS Suffix” of the on-board wired LAN interface.
     - Host Name – Takes the host name from the operating system. The suffix is blank.
     - Active Directory FQDN – The hostname part of the FQDN is the hostname from the host operating system. The suffix is the AD domain of which the host operating system is a member.
     - DNS Look Up FQDN – Takes the name returned by an “nslookup” on the IP address of the on-board wired LAN interface. To use this option, the DNS must be configured correctly with Reverse Lookup Zones.
   - Get the FQDN from the dedicated network settings file

     Note:
     If you select a dedicated network settings file as the source for the FQDN or IP: Make sure that the file contains only the settings (FQDN / IP) that you want to supply using the file. For information about the format and tags of the XML file, see the NetworkSettings.xml example file located in the sample_files folder. Do not forget to supply the path to the file using the /NetworkSettingsFile parameter of the Configurator CLI command.

2. (Optional) Intel AMT 6.0 and higher includes a setting called “Shared FQDN”. This setting can change the behavior of the Intel AMT device when using option 81 of the DHCP server to update DNS:
   - When this setting is true, the Intel AMT device will send broadcast queries only when the operating system is not running. This is the default behavior of all Intel AMT versions that do not support the Shared FQDN setting.
   - When false, the device will always send its own broadcast queries, even when the operating system is running. For Intel AMT 6.0 and higher devices that will be configured with a dedicated FQDN, clear this check box: The device and the OS will have the same FQDN (Shared FQDN).
3. From the IP section, select the source for the IP settings:
   - Get the IP from the DHCP server
   - Use the same IP as the host (for static IP only)
   - Get the IP from the dedicated network settings file
4. In the DNS section, define how Intel AMT 6.0 and higher will update the Domain Name System (DNS) with the FQDN and IP:
   - Do not update – Disables all DNS updates by the Intel AMT device.
   - Update only via DHCP option 81 – The device will use the DHCP option 81 to request that the DHCP server update the DNS on its behalf. On Intel AMT 6.x and 7.x systems, Intel SCS only supports this option on the latest firmware versions.
   - Update the DNS directly or via DHCP option 81 – Intel AMT 6.0 and higher includes the Intel AMT Dynamic DNS Update (DDNS Update) Client. When enabled, this client can periodically update the DNS with the FQDN and IP address configured in the Intel AMT device. When selected, the device uses option 81 to ask the DHCP for permission to update the DNS. Intel AMT will send DDNS updates based on the policy configured in the DHCP server returned in the DHCP option 81 flags.

     Note:
     All systems that have Intel AMT 5.x or lower are always configured to update the DNS via DHCP option 81. (This is the only option that those versions support.)

5. Click OK. The Network Settings window closes.
