How to block specific websites

Great question—and you're definitely not alone in this one! Blocking specific websites can be a little tricky depending on the setup, and I totally get how frustrating it is when it feels like you're doing everything right but it still doesn’t work.

With the XB8 Gateway, the built-in admin tool used to offer basic website blocking features, but they can sometimes be hit-or-miss—especially with websites that use multiple domains or HTTPS encryption (which most do these days). That’s likely why entering the site manually isn’t giving you the results you expected.

Right now, the best way to manage content and block specific sites is through xFi Parental Controls in the Xfinity app. While it doesn’t let you block specific URLs directly, you can pause devices, schedule offline times, and apply content filters for things like adult content, which helps a lot with general safety and control.

If you're looking for more precision—like blocking certain websites by name—you might consider adding a third-party tool like OpenDNS or using a router with more advanced parental controls alongside your XB8. Totally understand that’s not ideal, but it gives you much more control over individual websites.

We know these tools aren’t perfect yet, and we appreciate your patience—it’s something we’re always looking to improve. If you want help walking through the options or setting up one of those alternatives, we’ve got your back!
