Completing the Recorder’s Network SettingsBasic TCP/IP ConceptsThis section describes a few basic TCP/IP concepts. If you are familiar with homenetworking, you can skip to “Begin TCP/IP Settings” on page 126.• IP Address. TCP/IP settings are used to manage IP addresses on a network. An IPaddress is a number that identifies a single device on a network (in much the same waythat a home address identifies a single home in a town). IP addresses use four numbersseparated by periods. Each number can be from 0 to 255. Some example IP addressesare: ‘192.168.0.1’ and ‘10.8.3.25’.• DHCP and Static IP Addresses. DHCP automatically assigns IP addresses to deviceson a network. Most home networks include a router or home gateway that has DHCP.If your network has DHCP, or you are creating a peer-to-peer network, your Recordercan obtain its IP address automatically. An IP address assigned by DHCP is called adynamic IP address because it may change automatically as devices are added to orremoved from the network.If your network does not have DHCP, you must specify an IP address for your Recorder.An IP address you specify is considered a static IP address, because it will not changeuntil you specify a new one.If you assign a static IP address to your Recorder, remember that:• The first three sets of numbers in the IP address usually must match the first sets ofnumbers in the IP address used by another device on the network (for example, acomputer). The first three sets of numbers for IP addresses on a home network areusually: ‘192.168.0’ or ‘192.168.1’.• If the first three numbers match those of another IP address, the last number has to beunique. For example, two IP addresses for devices on the same network might be‘192.168.1.5’ and ‘192.168.1.6’.1257
