IP host

The IP host page displays the list of all the dynamic hosts, default hosts and manually added hosts.

Hosts allow the entities to be defined once, which can be re-used in multiple referential instances throughout the configuration. For example, consider an internal mail server with an IP address 192.168.1.15. Rather than repeated use of the IP address while configuring security policies or NAT policies, it allows to create a single entity internal mail server as a hostname with an IP address 192.168.1.15. This host, internal mail server can then be selected in any configuration that uses host as a defining criterion.

By using host name instead of numerical address, you only need to make changes in a single location, rather than in each configuration where the IP address appears.

Using hosts, reduces the error of entering incorrect IP addresses, makes it easier to change IP addresses, and increases readability.

You can group multiple entities performing the same function within a single hostname.
