An Efficient Cache Based Client Side DNS Resolution Approach

Web browsing is increasing day by day. As Internet has wide range of applications for everyone so internet users are growing exponentially. Every time when web browser loads any web page from internet server, browser first need to resolve Domain Name Server (DNS), server first converts domain name into IP address-a machine readable format. So hits on DNS is getting increase as search increases. Though DNS server is a distributed high end server but there is need of some mechanism by which we can reduce number of DNS query packets. There is need to reduce load of DNS. In this paper an effort is made to develop new method using cache consistency mechanism at client machine so that redundant requests from client is reduced and load of DNS server can be reduced and efficiency will increase.
