Hey guys, I want to test if IPSocket::getaddress(‘address’) is valid  
before printing it or anything…

If the user enters an invalid address then the program dies, i tried  
rescuing the error but i didn’t have much luck, any ideas?

Thanks in advance

Try creating a test first.  
Using testing facilities in Ruby is exactly for this kind of thing!
