Value Type


Accepted Values

yes | no

Default Value



This parameter specifies whether or not the DUT supports captive DNS, which is a DNS filtering feature that re-routes all outbound DNS requests to the DUT’s local DNS server.

This feature prevents LAN clients from bypassing any DNS based content filtering or parental control mechanisms that may be implemented within the DUT.

The cdrouter_app_30 and ipv6_app_112 test cases can be used to verify the DUT’s captive DNS functionality IPv4 and IPv6 based DNS requests, respectively.

This testvar was added in CDRouter 11.3
