Inet Address and I.P address confusion

Question

Hi,
I have an I.P address which I recieve from user input in four seperate variables each of type int. The reason I'm doing it this way is for increment purposes. Now the first initial IP address I want to ping to see if it's alive or dead. Then the program will increment the I.P address to check the next available IP address to see of that's alive or dead. Stupid University coursework Grrr :(.
What I was thinking (in theory anyway) is to convert all the digits from all four variables into the one I.P address and get that as an Inet Address object. From there I can use the object easier to Ping. Then I will clear that Inet Address object and increment variable four by 1 to create the next available IP address and then convert the new four variables into a Inet Address onject and ping that object and so on and so on.
Just wondering if in theory I'm on the right tracks or does this make no sense whatso ever? I'm still confused over it but kind of an idea. I'm sort of doing the projects as we learn the language and even though I read lots of tutorials on using Inet address I'm a bit stumped by this project. Any help really appreciate.
Thanks,
No longer a JavaNewbie but far from advanced!

I would also strongly suggest that you get in writing that you are supposed to be creating a port scanner.
People have been fired from their jobs and others expelled from their university when they were given an assignment that the security staff at the institution considered to be a security problem. And their superiors refused to back up the assignment (possibly because the axe would have gone their way.)
