Wildcards and Destination Lists
Every domain in a block or allow destination list has an implied left side and right side wildcard.
Note: Asterisks (*) are not supported.
| Allow or Block List Entry | Implied Wildcard |
|---|---|
| domain.com | *.domain.com/* |
| com | *.com/* |
| www.domain.com | *.www.domain.com/* |
It is not possible to use an asterisk to wildcard a different part of the domain. The following will not work:
- *.domain.com
- subdomain.*.com
- sub*.com
- domain.*
Adding domain.com to an allow list results in requests to domain.com or its subdomains, such as www.domain.com, being allowed. The result is the same for blocklists.
Wildcards also support top-level domains (TLDs), to allow broad allows or blocks. Use caution as adding a TLD to an allow list may open your network to malware threats, and adding a TLD to a block list may block more than expected due to CNAMEs and CDNs.
Note: Regular expressions in URL paths are not supported.
