it does no such thing as blocking, unblocking or hiding or changing ip or dns. it is a simple utility that does what you would do if you changed your dns addresses manually.
it cant save you from transparent dns if your isp has it configured, cause it still uses port 53.

you need encrypted or dns over https for that. or somehow proxy your dns request and not use port 53 to send dns plain dns request. so this is just an app that saves some clicks at best if you want to change your normal dns.
