title: List the IP Address of all computers connected to a single LAN
body: <p>I am writing a program where you connect, for various reasons, to other computers in a LAN. However, rather than having to input the IP address for multiple computers (a pain in the butt), I was wondering if there is a way to list the IP addresses of all the computers in a LAN. I have researched all day, and as of yet have found nothing suitable. Is this because nothing of this sort exists?
  Thank you in advance.</p>
  
  <p><strong>EDIT:</strong> It would seem that with the many views this post is getting, I should post my actual solution. In general, the naming conventions for computers IP addresses on a LAN are the same. example being 192.168.2.*, * being replaced with any valid number. My program detects the IP address, displays it to the user, then asks for the first 3 blocks of IP. It then sequentially scans up to 200 in the given IP naming convention by pinging and waiting for a response. No response, no computer. It can do everything you can do with an IP once it knows it has a computer behind it.</p>
