Chapter 7 Home Networking
you must enable the Network Address Translation (NAT) feature of the Zyxel Device. 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 Zyxel Device, but make sure that no other device on your network is using
that IP address.
