This is just a small page that I set up to see if there
are any web servers running on my local network.
Each one of the following links will open a page with
256 iframes corresponding to 256 ip addresses of the
chosen 255.255.255.0 network. Caution is advised as
opening up 256 pages can be quite noisy.
