Develop a basic DNS server (in C#) [closed]

Question

I am developing a very basic DNS server for my own purpose. The way I understand it, the DNS server receives UDP packets containing the requested domain name and returns the corresponding IP under some kind of standard form.

There is a standard library for reading/writing UDP packets from/to binary format. But where can I find a C# library for serialising/deserialising DNS requests/responses?

Answer 1

The open source ARSoft.Tools.Net library contains a DNS Server component (see documentation).

You could use this library directly, or just use the source as a starting point for building your own DNS request serializer.

Answer 2

As far as I can tell, I couldn't find a library for C# which handles DNS packet serialization/deserialization, which means it's likely you'll have to roll your own.

Edit: I came across this network packet sniffer project on Code Project which might have what you need. Claims to be able to to parse TCP/UDP/DNS

I did find this very helpful site for TCP/IP which has a pretty comprehensive set of pages describing DNS packet types including the general message format.

There might be some additional help from this previous SO question though.
