This option lets you specify the target TCP addresses to be scanned. Each target address has four parts with periods separating the parts, and can represent one or more IP addresses. Each part consists of a number between 1 and 254, a range of numbers, or a wildcard character (* or ?). A range of numbers is specified as n-m where n is the lower limit and m is the upper limit. If the lower limit is not specified (for example, -127), 1 is used. If the upper limit is not specified (for example, 17-), 254 is used. A * represents the range of numbers 1-254. A ? represents the matching part of the agent's IP address. These numbers, ranges of numbers, and wildcard characters can be used in combinations to specify complex sets of IP addresses. For example, if the range 172.17.10-20.* is specified, the addresses 172.17.10.1, ..., 172.17.10.254, 172.17.11.1, ..., 172.17.11.254, ..., 172.17.20.254 are scanned. The range of IP addresses an agent can scan is limited based on the Class of the agent's IP address.
