Can I use 188.8.131.52 instead of 184.108.40.206? Because 220.127.116.11 is faster for me than 18.104.22.168 and I got this test with dns benchmark software.
You sure can! So put 22.214.171.124 first, then 126.96.36.199 (or another favorite DNS) as a backup.
How is it faster? Can you provide the diagnostic information below?
188.8.131.52 and 184.108.40.206 should point to the exact same servers and have the exact same performance.
If one responded to a DNS query more quickly, it should just be because of luck – for example, it might have had to query the authoritative servers one time, but had the result cached the next time.
But if you’re being routed to different locations, or your ISP is intercepting 220.127.116.11 or something, that needs to be fixed.
