Design and implementation of a DNS server with Geolocation capability

In modern world, Domain Name System (DNS) is one of the major components that build the Internet as we know today. A DNS server with geolocation capability can answer a client depending on the geolocation of the client. Unfortunately, popular DNS server-side software solutions do not support the geolocation feature. In this paper, we design a DNS server, which has geolocation feature, and implemented it. Experimental results show that we can return different values based on the geolocation information of the client, so different clients may connect to the server that are nearest to them.
