Why not just try to connect to the server and see if that works?

I already connect with the server, but my question is that i want to check whether server is denied or exists..... means I wanna use a condition on ip address, whether IP exists or not ?

I don't think you can do that definitively. If the server chooses not to respond to you then you can't tell if it's there, or not there.
You could try to ping the server, but once again, if it decides not to respond then there's nothing you can do.

Well if the client is in java surround the statement which initiates the connection with a try catch statement that should help to see whether a connection was successfully made or not
