Speeding up the DNS Query in Linux

To speed up the DNS query in Linux , we can specify IP address of the domain that we frequently in the file--/etc/hosts
For example if we visit GOOGLE.COM often,to speed up the DNS Query we can specify as,


72.4.207.99 google.com

-in the file /etc/hosts.since the IP address in stored in local database there is no need to connect to DNS server.This we speed up the net connection.
