I used DNS benchmark software to test the reliability and speed of 6 main DNS servers(2 of the same companies). I wonder how Asus router use DNS servers; does it use the primary one first, then the second if it's not working? or does it use both at the same time? I also wonder if it is okay if I put 8.8.8.8(Google) as primary DNS Server and 208.67.222.222 as secondary DNS Server. Will it do any good compared to using both of the same company. What I found out is that even I used 8.8.8.8 and 8.8.4.4, for example, the reliability is not the best of the two(my router is set to use 8.8.8.8 and 8.8.4.4 as DNS Servers). Even if 8.8.8.8 reliability is 100% for uncached, sometimes the router uncached reliability is not 100%. I don't need any protection from DNS Servers, but having that does not matter either. What should I choose to be my router's primary and secondary DNS Servers then? Based on benchmarks below. The longer red tab on the left, the less reliability. For the 3 tabs, the longer the slower. Red is for cached benchmark, green is for uncached, and blue is for dot com. Is it possible to use 3 DNS servers in total? Will that do any good?
Add: My ISP DNS servers are less reliable and slower than Google DNS Servers(Thailand).
