How to choose DNS service

DNS service does not have absolute advantages or disadvantages, mainly depending on where you are, and generally the DNS node closest to you has the fastest response.

You can use the ping tool, for example:

$ ping -c 5
PING ( 56 data bytes
64 bytes from …..: icmp_seq=0 ttl=55 time=45.309 ms

The smaller the millisecond value, the lower the delay and the faster the response. In the Chinese network environment, if the average value is within 20ms, the network quality is very good.
