I recently got a new D-Link router and when I was setting it up it asked if I wanted to use Advanced DNS because it provides "Faster and more reliable Internet browsing" or something along those lines so I decided to enable it. Turns out one of the things it did was that every time I use my address bar to search it came up with search results quick "powered by yahoo" which I did not like so I disabled it.
I tried looking up what it even does and whether there are any noticeable benefits to enabling it but couldn't find anything. I did see a few things where it suggested you try OpenDNS or Google's Public DNS as an alternative but I don't really understand anything on this topic. I'm just wondering if anyone could explain why I would change from my ISP's to Automatic DNS or any other DNS like OpenDNS?
