The latency (time to respond) from your chosen DNS server, determines how quickly your web browser will find the IP address to load a website. You can choose other DNS servers apart from the default one you may get from your ISP.
But how do you know which DNS server will offer the best speed? The answer is simple: you need to check and compare the speeds of various DNS servers to find out which one works best for you.
To do this, you need to run a latency test, which measures how quickly your device is able to communicate with the DNS server, because the result I’m getting will not be the same for everyone.
This can be done by using various tools such as “dig” and “nslookup,” which allow you to check the speed of the DNS server by pinging it and then comparing its response time.
