Advantages of having own DNS
If I want to query a DNS then I can use some public ones like Google, CloudFlare etc. But they apply rate limits if you cross a certain threshold. What I have seen that the threshold is very high but still what if I want to use my own DNS. My questions are:
- Does it require high RAM or CPU i.e. the more the queries the more resources required? Is there some number available regarding this?
- From where will my DNS get data? Will my DNS request data from another DNS or will it store all data locally? I mean if it will get it from another DNS then it doesn't really serve my purpose because you are just forwarding request to another DNS, right!?
