Any existing DNS resolver project for windows? Both C++ or C# will do.

Question

I've been trying to build a DNS resolver in C# since last week, which is a painful process.

Though I've made some progress (say, I can parse the data of a DNS Message correctly), it became more and more likely to me that this may not be the right job for C#.

I have to be prepared in case I had to port to C++. But it is best not do it from scratch again.

So is there any project for Windows that can be used to parse a received DNS message or construct one to send?

Thanks.

Answer 1

bind has a whole suite of tools (with source code) for doing DNS queries and much, much more. It's liberally licensed (MIT-like license), so you can use it even in commercial projects.
