Block ads on Roku

As of March 2026, this has successfully blocked on-screen ads on Roku Stick Plus and a TCL-branded Roku TV.

Adapted from here.

1. Set a static DHCP reservation for the Roku device so it gets a known IP.
2. Create a firewall rule to block outbound DNS (TCP port 53) so that the Roku has to use your router's DNS. Specifically:
   • Source: Roku IP address (from above)
   • Destination: Any
   • Port: TCP 53
   • Action: Block/Drop
3. On your router's DNS server, black hole the following domains (including subdomains):
   • ads.roku.com
   • amarillo.logs.roku.com
   • amoeba-plus.web.roku.com
   • customer-feedbacks.web.roku.com
   • digdug-g2.logs.roku.com
   • digdug.logs.roku.com
   • ravm.tv
   • wwwimg.roku.com

Note: If you can't block domains on your DNS server, instead set the DHCP setting for the Roku to use OpenDNS (or whatever DNS filtering service), and do the filtering there.
