Prestige 128IMH ISDN Modem/ Router/Hub Collecting Ethernet Setup Information IP Address - An IP Address is required for TCP/IP protocol. The IP Address is the unique 32-bit number assigned to your Prestige. This address is written in dotted decimal notation (four 8-bit numbers, between 0 and 255, separated by periods), e.g., 192.168.1.1. Record the IP Address into the worksheet as assigned by your network administrator. Please note that every machine on an internet must have a unique IP address - do not assign an arbitrary address to any machine. If you are not sure as to which IP address to assign to the Prestige, contact your LAN administrator or refer to Chapter 4 of this guide for more details. IP Subnet Mask - This field is required for TCP/IP protocol. An IP address consists of two parts, the network ID and the host ID. The IP Subnet Mask is used to spe cify the network ID portion of the address, expressed in dotted decimal notation. The Prestige automatically calculates this mask based on the IP address that you assign. Unless you have special need for subnetting, use the default mask as calculated by the Prestige. The table below lists some examples of IP subnet masks and the number of hosts that are allowed. Consult your network administrator if you are unsure of this value.
