Earlier i used to run pihole in RPI 3+ when i was using asus router. Later once i moved to Google wifi router, i did not configure pihole and left it. Recently decided to setup pihole again as the Ads are too much now a days and most of the ads in mobile browser covers entire screen

. Since pihole needs a seperate setup and a device, i was looking for cloud based system, thats when i found out NextDNS. It was easy to setup and so far free account is fine for me. I configured NextDNS dns servers in my google wifi router and run a automatic task in Firestick to update my public IP to the NextDNS by calling their URL. Since firestick will be running almost whole day, i setup Automagic(alternative to tasker) to call the URL provided by NextDNS for every one hour.
So far this setup working fine.
