4.6 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.
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 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.
4.7 IP Address Assignment
A static IP is a fixed IP that your ISP gives you. A dynamic IP is not fixed; the ISP assigns you a
different one each time. The Single User Account feature can be enabled or disabled if you have either
a dynamic or static IP. However the encapsulation method assigned influences your choices for IP
address and ENET ENCAP Gateway.
4.7.1 IP Assignment with PPPoA or PPPoE Encapsulation
If you have a dynamic IP, then the IP Address and ENET ENCAP Gateway fields are not applicable
(N/A). If you have a static IP, then you
only need to fill in the IP Address field and not the ENET
ENCAP Gateway field.
4.7.2 IP Assignment with RFC 1483 Encapsulation
In this case the IP Address Assignment must be static with the same requirements for the IP Address
and ENET ENCAP Gateway fields as stated above.
