For example, if the IP address is: 172.16.0.10 and the Subnet Mask used is Class B (255.255.0.0), thefirst two groups of numbers (172.16) are ignored once they reach the proper network location. Thenext two groups (0.10) are the final destination within the LAN to which the connection is to be made.For sub-netted networks, the subnet mask may be different from the default subnet masks listed above.2.3 DHCPDynamic Host Configuration Protocol (DHCP) assigns a dynamic IP address. Network control may beeasier with DHCP as there is no need to assign and program individual IP addresses for the LANequipment. To use a dynamic IP address, a DHCP server must be provided. The SL2100 can beconfigured to be the DHCP server for the customers network. Before the DHCP server in the SL2100can be enabled, the DHCP client function must first be disabled.When equipment, which is connected to the LAN (the DHCP client), is requesting an IP address, itsearches the DHCP server.When the request for an address is recognized, the DHCP server assigns an IP address, Subnetmask, and the IP address of the router, based on NEC SL2100 system programming.SECTION 3 CONFIGURATION EXAMPLESThe following configuration examples illustrate a typical network configuration for an existing networkthat uses a static address and a typical configuration for a new network that uses a dynamic address.3.1 Example Configuration 1 - Existing Network with Static AddressingFigure 4-1 Example Configuration 1 - Existing Network with Static IP Address on page 4-3 shows atypical network configuration that uses Static IP Addressing.Each client device has a manually assigned IP address in the 192.168.1.0/24 network (i.e.,192.168.1.1 to 192.168.1.254 with a subnet mask of 255.255.255.0). They also have a defaultgateway address configured (192.168.1.254) this allows the device to route packets to destinationsthat exist outside of their own LAN.SL2100 ISSUE 1.04-2 General IP Configuration
