Prestige 100WH Internet Access Router IP Pool Setup The Prestige is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to 192.168.1.64. This configuration leaves 31 IP addresses (excluding the Prestige itself) in the lower range for other server machines, e.g., server for mail, FTP, telnet, web, etc., that you may have. DNS Sever Address(es) DNS (Domain Name System) is for mapping a domain name to its corresponding IP address and vice versa, e.g., the IP address of www.zyxel.com is 204.217.0.2. The DNS server(s) is extremely important because without it, you must know the IP address of a machine before you can access it. The DNS server address(es) that you enter in the DHCP setup is passed to the client machines along with the assigned IP address and subnet mask. Make sure that you obtain the IP address of the DNS server(s) from your ISP. Your workstations will need this information even if you don't use the Prestige's DHCP server. 3.2.4 More on IP Address and Subnet Mask Similarly to the houses on a street that share a common street name, the machines on a LAN share one 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. If you subscribe to an ISP and the ISP did not explicitly give you an IP network number, then most likely you have a single-user account. If this is the case, it is recommended that you select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing zero). 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 3 numbers specify the network number while the last number identifies an individual workstation on that network. 3-4 Chapter 3 Internet Access Application

IP Pool Setup
The
Prestige
is pre-configured with a pool of 32 IP addresses starting from 192.168.1.33 to
192.168.1.64. This configuration leaves 31 IP addresses (excluding the
Prestige
itself) in the
lower range for other server machines, e.g., server for mail, FTP, telnet, web, etc., that you
may have.
DNS Sever Address(es)
DNS (Domain Name System) is for mapping a domain name to its corresponding IP address
and vice versa, e.g., the IP address of
www.zyxel.com
is 204.217.0.2. The DNS server(s) is
extremely important because without it, you must know the IP address of a machine before
you can access it. The DNS server address(es) that you enter in the DHCP setup is passed to
the client machines along with the assigned IP address and subnet mask. Make sure that you
obtain the IP address of the DNS server(s) from your ISP. Your workstations will need this
information even if you don’t use the
Prestige
’s DHCP server.

More on IP Address and Subnet Mask
Similarly to the houses on a street that share a common street name, the machines on a LAN
share one 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.
If you subscribe to an ISP and the ISP did not explicitly give you an IP network number, then
most likely you have a single-user account. If this is the case, it is recommended that you
select a network number from 192.168.0.0 to 192.168.255.0 (ignoring the trailing zero). 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 3 numbers
specify the network number while the last number identifies an individual workstation on that
network.
