Host

Host is a way to associate an individual host's IP address with a name for the address object. FIGURE 5-17 shows the Address dialog box for adding a new host to the host subtype.

Range

Range associates a range of IP addresses with an address object name. For example, you can associate a name with a specified range of network IP addresses and use that name to filter traffic to all hosts on that network. FIGURE 5-18 shows the Address dialog box for adding a new range of addresses to the range subtype.

Group

Group is a way to group host addresses, address ranges and other address groups. By grouping addresses that use similar services and have similar actions, you can save time when creating rules. FIGURE 5-19 shows the Address dialog box for adding a new group to the group subtype.

Note -

Before you create an address group, you first define the address objects--single addresses, address ranges, or address groups--that you want to use in the address group.
