2.3.3. 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 specify 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.
