Recently saw a post regarding pi-hole, and I am considering to try it out. I am wondering if it would fit my usecase, so I want to ask about specifically what it solves.

I heard pi-hole blocks ads at DNS resolution level, so it does not block e.g. youtube ads. For me and my family who mostly watch youtube with handful of blog surfing, what value would it bring? Most blogs do not seem to contain much ads, so I am not sure ad-blocking helps much there.

Given the praise pi-hole is getting, I guess there are more to it than limited blocking of ads. I would love to learn more about this topic, as I am blind on the networking stuff. Thanks in advance!
