Wildcards and Domain Management

Every domain that you add to a domains list has an implied left side and right side wildcard. Wildcards support top-level domains (TLDs).

Domains List Entry	Implied Wildcard
domain.com	.domain.com/
com	.com/
www.domain.com	.www.domain.com/

Adding domain.com to a domains list results in requests to domain.com or its subdomains, for example: www.domain.com or www.domain.com/path.

Known Limitations

Umbrella does not support the following format of domains in domains lists:
- *.domain.com
- subdomain.*.com
- sub*.com
- domain.*
Umbrella does not support asterisks (*) in domains list entries. You can not use an asterisk (*) to wildcard a different part of the domain.
Umbrella does not support regular expressions in URL paths.
