I created a whole framework for UDP and TCP handling.

The main problem with DNS is, that the specification does not really exists.
It is mainly specified by the BIND source code. The main part is parsing old
BIND configuration files. Futhermore a non crashing implementation is not
secure. The protocol has several weaknesses itself an can't be implemented
the na�ve way.

Before you try to implement DNS, write a MTA, it's much easier.
Better: Write an FTP server.

Do not write an Telnet server, the Telenet protocol is too complex.

But if you really want to remove a common security hole, rewrite an ASN.1
parser. ftp://ftp.iks-jena.de/pub/mitarb/lutz/standards/itu-t/x/ contains
X.208 and X.209. The available library (libsnmp) is implemented in the C
preprocessor language and therefore nor linkable. So you are really free to
implement from scratch.

Good luck.
