The IP address or domain name of a trusted web site. Use a host name such as 
www.good-site.com. Do not use the complete URL of the site – that is, do not include 
“http://”. All subdomains are allowed. For example, entering “zyxel.com” also allows 
“www.zyxel.com”, “partner.zyxel.com”, “press.zyxel.com”, etc. Use up to 63 case-
insensitive characters (0-9a-z-).

You can enter a single IP address in dotted decimal notation like 192.168.2.5.

You can enter a subnet by entering an IP address in dotted decimal notation followed by 
a slash and the bit number of the subnet mask of an IP address. The range is 0 to 32.

To find the bit number, convert the subnet mask to binary and add all of the 1’s 
together. Take “255.255.255.0” for example. 255 converts to eight 1’s in binary. There 
are three 255’s, so add three eights together and you get the bit number (24).

An example is 192.168.2.1/24

You can enter an IP address range by entering the start and end IP addresses 
separated by a hyphen, for example 192.168.2.5-192.168.2.23.
