What You Need To Know; Address Summary Screen - ZyXEL Communications ZyWall ATP series User Manual

34.6.1 What You Need To Know

Address objects and address groups are used in dynamic routes, security policies, application patrol,
content filtering, and VPN connection policies. For example, addresses are used to specify where
content restrictions apply in content filtering. Please see the respective sections for more information
about how address objects and address groups are used in each one.
Address groups are composed of address objects and address groups. The sequence of members in the
address group is not important.

34.6.2 Address Summary Screen

The address screens are used to create, maintain, and remove addresses. There are the types of
address objects:
• HOST - the object uses an IP Address to define a host address
• RANGE - the object uses a range address defined by a Starting IP Address and an Ending IP Address
• SUBNET - the object uses a network address defined by a Network IP address and Netmask subnet
mask
• INTERFACE IP - the object uses the IP address of one of the Zyxel Device's interfaces
• INTERFACE SUBNET - the object uses the subnet mask of one of the Zyxel Device's interfaces
• INTERFACE GATEWAY - the object uses the gateway IP address of one of the Zyxel Device's interfaces
• GEOGRAPHY - the object uses the IP addresses of a country to represent a country
FQDN - the object uses a FQDN (Fully Qualified Domain Name). An FQDN consists of a host and domain
name. For example, www.zyxel.com is a fully qualified domain name, where "www" is the host, "zyxel" is
the second-level domain, and "com" is the top level domain. mail.myZyxel.com.tw is also an FQDN,
where "mail" is the host, "myZyxel" is the third-level domain, "com" is the second-level domain, and
"tw" is the top level domain.
Table 257 FQDN Example
HTTP://
In an address FQDN object, you can also use one wildcard. For example, *.zyxel.com. An FQDN is
resolved to its IP address using the DNS server configured on the Zyxel Device.
The Address screen provides a summary of all addresses in the Zyxel Device. To access this screen, click
Configuration > Object > Address > Address. Click a column's heading cell to sort the table entries by
that column's criteria. Click the heading cell again to reverse the sort order.
