Subnet designations
When designating a host in the configuration files, you can use a resolvable host name, an IP address, or a subnet. A subnet represents a range of IP addresses. In the configuration files, a subnet designation uses the following format:
@<IP address or hostname>/mask
The @ symbol indicates that a subnet is being defined. After the IP address or host name, provide the number of bits in the mask. For example, a subnet with a subnet mask of 255.255.255.0 might look like the following:
@192.168.10.0/24
The following are sample subnet mask definitions:
255.255.255.000 @192.168.100.0/24
255.255.255.128 @192.168.100.129/25
255.255.255.192 @192.168.100.193/26
255.255.255.224 @192.168.100.225/27
255.255.255.240 @192.168.100.241/28
255.255.255.248 @192.168.100.249/29
Tip: For faster searching, add an asterisk to the end of your partial query. Example: cert*
