DNS has nothing to do with ping response times. A ping requests the IP address from the DNS server and then does the ping. On most systems the DNS is cached locally, so multiple requests will use the same information.

Not true, the feature is called GeoDNS and gives you different IP addresses for the same domain based on your DNS server. See Locke1689's reply.
