Expected Behaviour:
Ads should be blocking when using clients to browse web (Windows 10 PC and Android Phone)
Actual Behaviour:
DNS lookups from Windows and Android are resolving normally. Browsing web from the computer that Pi-hole is installed works properly; ads are blocked.

I installed the latest version of Pi-Hole on my Intel Mac Mini running Debian 9. The IP address of the Pi-Hole server is 192.168.1.12. I am able to connect to the web interface from other devices.
I changed the DNS server on the Windows machine to the Pi-Hole server, yet no ads are blocked.
It returned this IP because the DNS request did not go through Pi-Hole. The domain doubleclick.com is blocked by the default Pi-Hole block lists. It is likely that your router is providing an alternate DNS path that bypasses Pi-Hole. If you are not actively using IPv6, disable this on your router and clients. This is a frequent source of bypasses.
