# ViewAllowedHostsList

A comma-separated list of hosts, specified by host name or IP address, that can be accessed to view documents. (Hosts that the View action can access when they occur in the Reference parameter).

- If an entry includes a port number, only that port is allowed.
- When you set this parameter or ViewAllowedURLsList, any URL that is not explicitly allowed is blocked.
- URLs that match ViewBlockedHostCSVs or ViewBlockedURLsCSVs are blocked, even if the host matches a value specified by this parameter.

NOTE: You cannot use IPv6 IP addresses.
