If you do much network design you're certainly familiar with the concept of subnetting, you probably even learned to do it by hand at one time. For those who are looking for an automated subnet calculation utility you can find a web-based one which requires no download or installation and supports subnets, supernets, CIDR and wildcards at subnet-calculator.com. The only real concern I have with this great utility is that the source code has not been provided so if the website goes offline you're out of luck. In the long term timeframe I would like to write an open source version of this utility so anyone can run it on their intranet or another website. If anyone is interested in helping to write the code for this in PHP please contact me and I'll move it up the list of priorities.
