Interface zones

Each domain always has an assigned interface zone with the same name. This is an object zone.

This zone is the only interface that makes the domain available to higher-level domains, so-called parent domains. Any object zones from the parent domain can receive the interface zone as a subordinate sub-zone.

You can link this interface zone to other object zones in the same domain. This allows you to pass on the content of individual object zones to higher-level domains via the interface zone.

All zones that are linked to the interface zone are called shared zones, as these zones are available in a higher-level domain. The zones that are not linked to the interface zone and are therefore not available in a higher-level domain are called local zones.
