-Chromecasts generally ignore DNS servers from DHCP and will instead use Google's DNS servers, 8.8.8.8 and 8.8.4.4. This means media URLs must either be specifying the IP-address of the server directly, e.g. `http://192.168.1.1:8123/movie.mp4`, or be publicly resolvable, e.g. `http://homeassistant.internal.mydomain.com:8123/movie.mp4` where `homeassistant.internal.mydomain.com` resolves to `129.168.1.1`. A hostname which can't be publicly resolved, e.g. `http://homeassistant.local:8123/movie.mp4` will fail to play.

 This is important when casting TTS or local media sources; the cast integration will cast such media from the `external_url` if [configured](/docs/configuration/basic), otherwise from the Home Assistant Cloud if configured, otherwise from the [`internal_url`](/docs/configuration/basic). Note that the Home Assistant Cloud will not be used if an `external_url` is configured.
