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 ADSL Router. 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, 192.168.1.254, for the ADSL Router, 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. The ADSL Router 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 ADSL
Router 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.
