Problem this snippet solves:

The following is an example how powerful the LTM in terms of hosting web pages w/o the necessity of having a physical web server. This technique can sometimes save you from purchasing or taking up valuable resource on a production web server for hosting a webpage.

This particular iRule throws up a network calculator which was coded by Al Vonkeman (http://www.subnetmask.info./)).

NOTE: The website does initially load up slowly. Thereafter it performs quickly as the processing is client side.

This doesn't work properly on 11.5.3. I haven't tested anything else. The Subnet calculator here: http://jodies.de/ipcalc works much better for my needs. If that could be converted into an iRule that would be fantastic!
