I have another one if you don't mind

I'm writing a chatting client - server using UDP (if anyone has a source code,
please, i'm waiting ;) )

anyway

In the client, I need to specify the address of the server

InetAddress IPAddress = InetAddress.getByName("hostname");

but I need to put the IP directly

I found something like this following:

byte[] myIP = "194.170.15.187".getBytes();

InetAddress IPAdd = InetAddress.getByAddress(myIP);

but it didn't work
