Page 1 of 14Naim Audio HDX Hard Disk Player – Network SetupNetworking BasicsAll devices that connect to a network have an Internet Protocol (IP) address. This address isused as a unique identifier on the network and allows communication between devices tobe routed correctly. IP is the standard used by all network devices.A typical home network will use a Modem/Router to connect to the Internet and will have anumber of devices connected directly to the Modem/Router. The Modem/Router acts as aswitch to allow intercommunication between the devices on the home network (LAN) andallows each of the devices to access the Internet (WAN). The Modem/Router also offerssignificant protection to the devices on the LAN side as they cannot be contacted directly bya computer on the WAN side without the LAN side device initiating the communication. TheHDX should never be connected directly to the Internet without a Router in place.It is usually the Modem/Router that allocates IP addresses to the different devices on thehome network. The process of dynamically allocating addresses to devices is known as DHCPand the part of the Modem/Router responsible for this is the DHCP Server. This system allowsdevices to be connected and disconnected without the user having to make anyadjustments to the device configurations. Because this system is the most common andconvenient for home use the HDX ships with DHCP mode enabled.
