1. comparing sonarr and radarr does not make sense, they are different projects.
2. we do not control your DNS
3. we support the container, not the application within the container. radarr has its own support, though this is more likely a host issue.
4. My radarr container is able to resolve everything on my network, implying this is a host issue on your side (see bullet 2)
