Adding wildcards to your block or allow lists is accomplished by an implied wildcard. Please see the examples below for the syntax of wildcards. Please note that the use of "*" is not supported in the domain lists to apply a wildcard.
| Always/Never Block Entry | Implied Wildcard |
| domain.com | *.domain.com |
| com | *.com |
| www.domain.com | *.www.domain.com |
Wildcard types that are not currently supported: subdomain.*.com, sub*.com, or domain.*
In the below example, since facebook.com is on the Always Block list, any requests to facebook.com or its subdomains, such as images.facebook.com and connect.facebook.com, will be blocked on this network.
Since wikipedia.org is on the Never Block list, any requests to wikipedia.org or its subdomains, such as en.wikipedia.org, will be allowed on this network.
