I suspect this question might be more suitable to networking stack exchange but I didnt find any such site, so this seemed like the best place to ask it.
I recently moved back to my native country and though the internet speeds here are tolerable, often the DNS server of the local ISP exchange goes down leaving me without internet for a couple of days or so. I was wondering if I could use the Google DNS or OpenDNS to connect to the internet when the ISP DNS was down , but I was not sure I needed a working DNS server in my local ISP to resolve the Google DNS
Please migrate or close this question if you feel its in the wrong section.
