1.3 Zyxel One Network (ZON) Utility
ZON Utility is a program designed to help you deploy and manage a network more efficiently. It detects 
devices automatically and allows you to do basic settings on devices in the network without having to 
be near it.
The ZON Utility issues requests via Zyxel Discovery Protocol (ZDP) and in response to the query, the device 
responds back with basic information including IP address, firmware version, location, system and model 
name in the same broadcast domain. The information is then displayed in the ZON Utility screen and you 
can perform tasks like basic configuration of the devices and batch firmware upgrade in it. You can 
download the ZON Utility at www.zyxel.com and install it on your computer (Windows operating system).
