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