You can build a host definition for a single IP address, or for a range of addresses.
The IP address specified to identify the host must always be made up of four elements separated by periods (.). You can enter a specific value, a range, or a mask for each element. The dash (-) is used to specify a range and the asterisk (*) is used as a mask. These can be used in combinations, for example, 192.168.80.*, 172.24.10.15-30, and 192.168.16-24.*.
Performance monitoring and diagnostic functions take the definition that more clearly represents that IP address. For example, 172.16.0.0 overrides *.*.*.* settings.
Important! You must not use ranges that overlap when you define community names. For example, the following IP address ranges will cause an error condition:
192.168.10.15-30
192.168.10.20-40
