Blocking youtube Android app from router

I was wondering how can I block the Youtube Android app from the router it self?

My router has a function to block a web address or an ip address.

It's TP-Link model TL-WR940N.

So does anyone know what website/IP address should I block to make the Youtube App not able to connect?

Adding to the previous list, the best way I've found to block YouTube content from desktop/laptop computers, iOS, and Android apps is by blocking the following list of URLs on your router/firewall:

• youtube.com
• www.youtube.com
• m.youtube.com
• ytimg.com
• s.ytimg.com
• ytimg.l.google.com
• youtube.l.google.com
• i.google.com
• googlevideo.com
• youtu.be

This should block all access on Macs/PCs. Mobile apps will still launch, and perhaps display some UI, but the videos themselves should be suppressed.

Try to block these sites in your router: googlevideo.com, l.google.com.

Other YouTube domains, you might consider blocing also includes: youtube.com, m.youtube.com, youtu.be, ytimg.com.

You can block Youtube by blocking below URLs:

youtube.com
m.youtube.com
youtu.be
ytimg.com
