 Now I have a best idea that is to clone a chating system in PHP.  I must squeze time to develop it.  Last night
I thought how to design a dynamic domain names system.  Teacher Hong told me its mechanism.  Once a client connect to a dynamic domain names server, that server can fetch the ip from a data datagram comed from the client.  It can register a client name and its ip.  So, when other accessers asking for it can tell them.

  As usual, user access resource though their browers, such as IE, Firefox, Opera, and so forth.  However, how to redirect to our dynamic domain names server when typing a client name?  In my viewpoint, it is a key.

  I don't know Hong how to solve it.  Under this circumstance, I need more the knowledge on network.
