Description

Unless EnableMediaRouter is set to Disabled, setting MediaRouterCastAllowAllIPs to Enabled connects Google Cast to Cast devices on all IP addresses, not just RFC1918/RFC4193 private addresses. Setting the policy to Disabled connects Google Cast to Cast devices only on RFC1918/RFC4193. Leaving the policy unset connects Google Cast to Cast devices only on RFC1918/RFC4193, unless the CastAllowAllIPs feature is turned on.
