I was always told by colleagues 126.96.36.199 appears to work faster and have to combine that with Google's public DNS. Basically using 188.8.131.52 as primary and 184.108.40.206 as secondary. However, Google only provides 220.127.116.11 and 18.104.22.168, so who provides 22.214.171.124? And if true, why is 126.96.36.199 faster?
Note: These IP addresses are used to dig domains and to determine if local DNS changes has propagated over all over the internet.
