ZyAIR
Chapter 5
IP Screen
This chapter discusses how to configure IP on the ZyAIR.
5.1Factory Ethernet Defaults
The Ethernet parameters of the ZyAIR are preset in the factory with the following values:
•IP address of 192.168.1.11
•Subnet mask of 255.255.255.0 (24 bits)
These parameters should work for the majority of installations.
5.2TCP/IP Parameters
5.2.1 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.
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, 192.168.1.11, for your ZyAIR, 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 ZyAIR 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 ZyAIR unless you are instructed to do otherwise.
Every computer on the Internet must have a unique IP address. If your networks are isolated from the Internet, for instance, only between your two branch offices, you can assign any IP addresses to the hosts without problems. However, the Internet Assigned Numbers Authority (IANA) has reserved the following three blocks of IP addresses specifically for private networks.
