43.7 Address/Geo IP Overview
Address objects can represent a single IP address or a range of IP addresses. Address groups are
composed of address objects and other address groups.
• The Address screen (Section 43.7.2 on page 841) provides a summary of all addresses in the Zyxel
Device. Use the Address Add/Edit screen to create a new address or edit an existing one.
• Use the Address Group summary screen (Section 43.7.3 on page 845) and the Address Group Add/
Edit screen, to maintain address groups in the Zyxel Device.
• Use the Geo IP screen (Section 43.7.4 on page 847) to update the database of country-to-IP address
mappings and to manually configure country-to-IP address mappings.
43.7.1 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.
