How to Create Wildcard Network Objects

Wildcard network objects are network objects that include a network mask containing information regarding which parts of the IP address is to be evaluated. Wildcard network objects can be used to describe IP addresses that cannot be covered by network objects using subnets masks.

Examples

Wildcard network objects are entered in the format IP address/network mask:

  • 0.0.0.1/0.0.0.255 = *.*.*.1

  • 0.200.0.0/0.255.0.0 = *.200.*.*
