66Network TerminologyGeneral information The Switch ensures that the individual components within a network areconnected correctly. This is only possible if it can identify each device withinthe network unambiguously; this is the reason why every component isassigned a form of “house number” (IP address). The IP address consists offour number blocks each containing three digits separated by dots (e.g.192.168.1.1).Each of the individual number blocks may contain values between 1 and 254(the values 0 and 255 are reserved for certain special functions, and shouldtherefore not be used). However, if the network is to operate reliably, thenetwork owner should only select addresses designed for home network use- i.e.: the first two number blocks should always be 192.168.xxx.xxx; thethird block can be selected without restriction within the above limits (butshould be the same for all devices on the network), and the fourth blockmust distinguish each device uniquely (e.g.: SDV 3100 HV 192.168.001.001,NAS: 192.186.001.002, PC: 192.168.001.003, ...).If this local network is to include Internet music sources (Internet radio) aswell as physical devices, then the SDV 3100 HV must have access to theInternet. This facility is provided by a device such as a router with connectionto the DSL network. This router is also a constituent part of the network, andis assigned its own IP address. The SDV 3100 HV must also be informed ofthe address of the router (Gateway) to enable it to gain access to the outsideworld. Please ensure that the first three blocks of the Device IP, Gateway IP andDNS 1 share the same address space (e.g. 192.168.0.xxx). The fourth blockassigns a unique address (house number) to the components in the localnetwork. This number must not be present more than once in the localnetwork.The Device IP mask should always be assigned the address 255.255.255.0.DNS The Domain Name System (DNS) is one of the most important services on theInternet. Its primary task is to convert “Internet addresses”, such aswww.taelektroakustik.de, into the associated IP address. In most homenetworks the router carries out the DNS function.If you decide to configure your network manually (without DHCP), thensimply enter the address of your router as the DNS address when configuringthe network.Ethernet-LAN Wired network. Interference-free network technology, with the drawback ofhaving to deploy a network cable.Gateway The computer or router in your network which is responsible for managingdata traffic between your home network and the outside world (i.e. theInternet).Client Network device which obtains data from the network, decodes it andconverts it into, for example, analogue music signals which can then bereproduced via an amplifier and loudspeakers. Streaming Clients alsocontain functions for displaying media content, and for navigating on theInternet or servers.DHCP DHCP is an abbreviation of Dynamic Host Configuration Protocol. Theprimary purpose of DHCP is to enable Clients to obtain your networkconfiguration automatically from a server or router.IP-Address Network address. Each device in the network requires an IP address at whichit can be accessed, and by which it is unambiguously identifiable. Noindividual network address may be present more than once. This isimportant if you are entering network addresses manually. If the addressesin your network are assigned by DHCP, you do not need to worry about IPaddresses at all, as the DHCP server manages the addresses automaticallywithout your intervention.
