Exactly.  The best part is it doesn&#x27;t even need to be blocked in the client.  I&#x27;m running Pi-Hole:<a href="https:&#x2F;&#x2F;pi-hole.net&#x2F;" rel="nofollow">https:&#x2F;&#x2F;pi-hole.net&#x2F;</a> with DNS Crypt:<a href="https:&#x2F;&#x2F;dnscrypt.org&#x2F;" rel="nofollow">https:&#x2F;&#x2F;dnscrypt.org&#x2F;</a> on a couple of Raspberry Pi 2s on my network acting as internal caching name servers.  Sure, I also run uBlock, but I don&#x27;t even see ads on mobile apps because they&#x27;re all blocked via DNS long before the client even has to parse it.
