DNS Server(repost)

Need a light weight DNS server that will be written in C or C++, I will need to be able to run it from VS6 and above. The API will be used from my process (you will be inside my process and not as a seperate process), also my calls to you may come from different threads so you need to protect the list. I will supply the server the IP and port to bind to, and the name of the domain to serve (also number of threads for the server, it should be multi threaded) After the server is running I will be able in runtime to add or remove entries to the server, the entries will be only A records. (the add/remove methods may be called from multiple threads, make sure to be able to handle it) For example suppose my domain it [login to view URL] then I will supply test1 [login to view URL] test2 [login to view URL] Then the server will know how to answer to requests to [login to view URL] and [login to view URL] The entries will be kept in memory, no need to store to file, it will support only UDP, it will also need to know how to answer to requests for other domains with a response that it will not serve that request. I also need a method to stop the server. To summarize: 1. Start the server with ip, port, domain and number of threads 2. Add/remove A records on the fly 3. Method to stop the server If you are using 3rd party code, All used code license can't be in form of GPL, LGPL, GNU.
