A Simple DNS Resolver
A simple DNS resolver compiled under Bloodshed C++ and using the Winsock 1.1 API
Introduction
This is my first socks program. Actually, it's the first one I completed since I want to test it's fuctionality before adding it to my main project. It is a simple DNS resolver using the Winsock API (v1.1). The program is a console application that accepts hostname or IP address parameters which will be resolved using gethostbyname and/or gethostbyaddress functions.
I really had a hard time of looking for a DNS query code in the net using the winsock API so I decided to try and make one myself. I have actually tested the program and it works. Of course, you need an internet connection to query DNS outside your network, and if the IP/host you queried is dead or has no reverse DNS then it would just state a DNS lookup failed!
The source code has comments on it and is fairly understandable for intermediate and perhaps beginners in winsock programming. It is mainly focused on the hostent structure since I had a hard time implementing it before. It is compiled in Dev-C++ which you could download at http://www.bloodshed.net/ using its default libraries. I've also placed some comments on the source code for information on how to compile it.
