Situation: I have an own network running which entails also a DNS server. I entered it as the preferred lookup server in the DNS settings. So far so good. But now imagine that for some reason my DNS infrastructure is not reachable at some point in time. As a no names can be resolved anymore (no alternative DNS server set ATM), and the client becomes unusable for surfing/working.
Question: What should I enter as the alternative DNS server?
Previously when using the auto-option I assume that windows was deicing which one is the best to use at the moment (couldn't find any info how windows decides). I am aware that there are some tools out that that claim to help to decide which one is the best in the current situation. But given that this client is a laptop and will often (sometimes daily) change its physical and network location, that is impractical.
I read that Google's DNS server (184.108.40.206) is said to be a good general choice (and fast thanks to the worldwide coverage and usage of anycast/geocast). Would that be your recommendation?
Or should I even add multiple servers via the "Advanced" button? Would that offer any benefits = would Windows occasionally go through that list and determine which of those is currently the best?
