Unable to perform DNS resolution in docker container

Any container that i start is failing to perform nslookup.

I started a centos 6.9 and nslookup is timing out.
;; connection timed out; trying next origin
;; connection timed out; no servers could be reached

The containers are getting resolv.conf file from the host machine as expected.
