Blacklists - xorlab

Blacklists are accessible by selecting Settings → Lists → Blacklists in XCC.

SubdomainsWhen you add a root (top-level) domain, e.g., example.com, to the list, all its subdomains will also be blacklisted. When you add a particular subdomain, e.g., site.example.com, only this subdomain will be blocked; any lower-level ones such as other.site.example.com won’t be affected.
