Configuring IP Addresses

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. 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. You must
also enable Network Address Translation (NAT) on the WAP3205.
Once you have decided on the network number, pick an IP address for your
WAP3205 that is easy to remember (for instance, 192.168.1.1) 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
WAP3205 will compute the subnet mask automatically based on the IP address
