# ViewBlockedHostCSVs

A comma-separated list of host names or IP addresses that you want to block so that the View action cannot access them when they occur in the Reference parameter. If you use this parameter to block addresses, the View component performs a host name lookup, and blocks both the IP address and host name for a particular site.

NOTE: You cannot use IPv6 IP addresses.
