How do you test your tutorials?

Technical & DNS Questions

Does Private DNS really block ads without an app?

Yes. On Android 9 and newer, setting an ad-blocking resolver like dns.adguard-dns.com in Private DNS filters domain lookups at the operating system level, so ad servers are refused across all apps without battery drain or background apps.

Why do YouTube ads still appear when using DNS ad blocking?

YouTube serves advertising videos from the same media domains and CDN servers as regular video content. Because a DNS filter blocks entire domains, it cannot separate YouTube ads from the video itself without breaking video playback completely.
