Address Ranges

An address range is a set of numerically contiguous IP addresses. Networks and subnetworks are typically identified by an IP address range name. You use the beginning and ending addresses to identify an IP address range.

You can set up an address object to represent an address range in SunScreen. FIGURE 3-3 shows examples of ranges of addresses for the Corporate and Sales networks. For example, the Corporate address object is defined as a range of addresses from 172.16.3.2 to 172.16.3.255. You could then establish access or encryption rules for hosts on the Corporate network by indicating the rule applies to the Corporate address object.
