C# Dns Proxy with M.I.T.M capability

C# Dns Server

C# Console application, that mirrors google's dns server (8.8.8.8) and can modify traffic (MITM mode)
Two MITM functions are available:

• Dropping Response
• Redirecting Response (replying with a fake ip address to the request) A.K.A Dns Spoofing

The program has a class which can serialize a DNS request/response, deseralize a DNS request/response.
So you have full control above the dns request sent and the response received.

c-sharp-dns-server's Issues

Issue with serializeLabel method

There is no null handing for "full" parameter

private string serializeLabel(out int length, string question, out string rest, string full = "")

if (currentBit == "C0")
in above condition if full parameter is null it throws exception on below line,
string data = full.Substring(offset);

What is current bit and what are all these conditions if you have any documentation around it please do share.
