Domain List

You can use placeholder characters in domain lists to configure a single entry to match against multiple website subdomains, pages, including entire top-level domains, as well as matches to specific web pages.
Follow these guidelines when creating domain list entries:
  • Enter each domain name in a new line; URLs or IP addresses are not supported in this list.
  • Do not prefix the domain name with the protocol, http:// or https://.
  • You can use an asterisk (*) to indicate a wildcard value.
  • You can use a caret (^) to indicate an exact match value.
  • The following characters are considered token separators: . / ? & = ; +
    Every string separated by one or two of these characters is a token. Use wildcard characters as token placeholders, indicating that a specific token can contain any value.
  • Wildcard characters must be the only character within a token; however, an entry can contain multiple wildcards.
When to use the asterisk (*) wildcard:
Use an asterisk (*) wildcard to indicate one or multiple variable subdomains. For example, to specify enforcement for Palo Alto Network’s website regardless of the domain extension used, which might be one or two subdomains depending on location, you would add the entry:
*.paloaltonetworks.com
. This entry would match to both docs.paloaltonetworks.com and support.paloaltonetworks.com.
You can also use this wildcard to indicate entire top-level domains. For example, to specify enforcement of a TLD named .work, you would add the entry
*.work
. This matches all websites ending with .work.
The (*) wildcard can only be prepended in domain entries.

tools.company.com
docs.company.com
*.click
all websites ending with a top-level domain of .click.
When to use a caret (^) character:
Use carets (^) to indicate an exact match of a subdomain. For example,
^paloaltonetworks.com
matches only paloaltonetworks.com. This entry does not match to any other site.
