When a **target domain** is listed, any website can access that specific local network resource without restrictions.
For example, if `"printer.local"` is listed, all websites can access the printer device.

Suffix wildcard patterns are supported using the `*.` prefix to match all subdomains:

- `"*.company.com"` - Skips checks for all subdomains of company.com (matches `app.company.com`, `portal.company.com`, etc.).
- `"*.internal"` - Skips checks for all .internal domains (matches `device.internal`, `printer.internal`, etc.).
- `"*.company.com"` - Skips checks for company.com and all subdomains (matching `company.com`, `app.company.com`, `portal.company.com`, etc.).
- `"*.internal"` - Skips checks for all .internal domains (matching `internal`, `device.internal`, `printer.internal`, etc.).
- `"web-app.example.com"` - Skips checks for this specific domain only (no subdomain matching).
- `"*.devices.local"` - Allows access to all local devices with `.devices.local` suffix (`printer.devices.local`, `scanner.devices.local`, etc.).
- `"*.devices.local"` - Allows access to all local devices with `.devices.local` suffix (matching `printer.devices.local`, `scanner.devices.local`, etc.).
- `"*.corp.internal"` - Allows access to all corporate internal domains.

A `*.` prefix pattern includes the domain itself, so you do not need a separate entry for it.
This means `"*.microsoft.com"` matches `microsoft.com` as well as `login.microsoft.com`.
An entry without the `*.` prefix matches the host only, so `"microsoft.com"` will not match `login.microsoft.com`.
