Visual Subnet Calculator

October 22, 2002 by davidc

This tool lets you quickly subnet IPv4 networks, visualise them, and split or join them with a single click. It also shows the address range, subnet mask, and number of hosts for each subnet. You can save and load your arrangement using bookmarks.

Access the Visual Subnet Calculator.

This was written in 2002, though I still use it constantly. One day I intend to make an equivalent for IPv6.

This subnet is very helpful, hopefully it's gave the availability to make good access with the bookmarks and other functions. I have read from college paper for sale on this subnet and it's extremely helpful. Lets hope for the recent updates from them.

Thanks

Thanks for creating this calculator. I didn't see any restrictions on use of the code so I put in a line attributing the original code to you. I did some minor modifications like embedding the images into the page so I could easily use it from a SharePoint site.
