Sorry my mistake.
After checking the documents I just know what's the difference between
Caching server and auth-server for DNS queries.
So it seems I am using a caching server whose IP addr is 127.0.0.53.
But isn't this addr a loopback IP? I was not sure about it.
I was thinking the caching server should be 8.8.8.8 etc.

Can you help with it? thanks in advance.
Help with what exactly? What is wrong with this DNS reply for you?
Seems totally legit.
what the helps I asked is that this server (127.0.0.53) returns many
timeout during my modperl querying process.
I think I may ask the sysadmin to add more caching servers and make them
have good network connection with internet, am I right?
thanks & regards.
