IP Configuration

IPv4 Configuration

Parameter	Description	Settings
Obtain an IP address automatically using	Used to select the mode for assigning the IPv4 parameters set. Obtain IPv4 parameters automatically using BOOTP or DHCP. NOTE: While using a legacy DHCP server, the device name must be limited to 16 characters.	DHCP (Factory setting) BOOTP
Manual IP address	Used to enter the static IP address of an IFE server.	–
Manual Subnet mask	Used to enter the Ethernet IP subnet mask address of your network.	–
Manual Default gateway	Used to enter the gateway (router) IP address used for wide area network (WAN) communication.	–

IPv6 Configuration

Parameter	Description	Settings
Enable IPv6	Defines the IPv6 configuration.	Enabled (Factory setting) NOTE: The setting is unavailable to edit.
Link local address	Used to open the IFE webpage for future use. NOTE: In the URL address box, use [ ] brackets to enter the link local address.	–

DNS

Parameter	Description	Setting
Obtain DNS address automatically	Defines the dynamic behavior of the DNS server address configuration. Used to obtain the IP address from the DNS server automatically. NOTE: Domain name system (DNS) is the naming system for computers and devices connected to a local area network (LAN) or the Internet.	Disabled when manual setting is selected.
Manual Primary server address	Defines the IPv4 address of the primary DNS server.	–
Manual Secondary server address	Defines the IPv4 address of the secondary DNS server. Used to perform a DNS resolution when the resolution fails with the primary DNS server.	–

Duplicate IP Address Detection

While connected to your network, the IFE server publishes its IP address. To avoid any duplicate IP address conflicts, the IFE server uses the address resolution protocol (ARP) to see if any other device on your network is using the same IP address. The following table explains how the IFE server handles a duplicate IP address when it is detected.

Duplicate IP Address Scenario

Scenario	Duplicate IP Detected	Network Status LED
Ethernet link detected	Reverts to the default IP address, subnet mask, and gateway address. ARP requests are sent every 15 seconds until the IP address is available. IFE server uses the IP address when it is available,	Steady red
Manual address change	Reverts to the default IP address, subnet mask, and gateway address. The ARP requests are sent every 15 seconds until the IP address is available. The IFE server uses the IP address when it is available.	Steady red
Receives an ARP request	If more than one ARP is detected within 10 seconds, initiate the process to reacquire the IP.	OFF
