Ethernet Setup
6.2 Ethernet TCP/IP and DHCP Server
The Prestige has built-in DHCP server capability that assigns IP addresses and DNS servers to systems that
support DHCP client capability. For remote node TCP/IP configuration, refer to the chapter on Remote Node
Configuration.

Configuration.
6.2.1 Factory Ethernet Defaults
The Ethernet parameters of the router are preset in the factory with the following values:
1. IP address of 192.168.1.1 with subnet mask of 255.255.255.0 (24 bits).
2. DHCP server enabled with 32 client IP addresses starting from 192.168.1.33.
These parameters should work for the majority of installations. If the parameters are satisfactory, you can
skip to section 6.3 to enter the DNS server address(es) if your ISP gives you explicit DNS server address(es).

6.2.2 IP Address and Subnet Mask
Similar to the way houses on a street share a common street name, so too do computers on a LAN share one
common network number.
common network number.
Where you obtain your network number depends on your particular situation. If the ISP or your network
administrator assigns you a block of registered IP addresses, follow their instructions in selecting the IP
addresses and the subnet mask.

addresses and the subnet mask.
If the ISP did not explicitly give you an IP network number, then most likely you have a single user account
and the ISP will assign you a dynamic IP address when the connection is established. If this is the case, it is
recommended that you select a network number from 192.168.0.0 to 192.168.255.0 and you must enable the
Network Address Translation (NAT) feature of the Prestige. The Internet Assigned Number Authority
(IANA) reserved this block of addresses specifically for private use; please do not use any other number
unless you are told otherwise. Let's say you select 192.168.1.0 as the network number; which covers 254
individual addresses, from 192.168.1.1 to 192.168.1.254 (zero and 255 are reserved). In other words, the first
three numbers specify the network number while the last number identifies an individual computer on that
network.

Once you have decided on the network number, pick an IP address that is easy to remember, for instance,
192.168.1.1, for your Prestige, but make sure that no other device on your network is using that IP address.

The subnet mask specifies the network number portion of an IP address. Your Prestige will compute the
subnet mask automatically based on the IP address that you entered. You don't need to change the subnet
mask computed by the Prestige unless you are instructed to do otherwise.
