23.7.2.2 Wildcard Patterns

You can use the following patterns in service or client addresses:

• A string that begins with a dot character (.). A host name is matched if the last components of its name match the specified pattern. For example, the wildcard pattern.siroe.com matches all hosts in the domain siroe.com.

• A string that ends with a dot character (.). A host address is matched if its first numeric fields match the specified pattern. For example, the wildcard pattern 123.45. matches the address of any host in the subnet 123.45.0.0.

• A string of the form n.n.n.n/m.m.m.m. This wildcard pattern is interpreted as a net/mask pair. A host address is matched if net is equal to the bitwise AND of the address and mask. For example, the pattern 123.45.67.0/255.255.255.128 matches every address in the range 123.45.67.0 through 123.45.67.127.
