“CIDR calculation” seems to be something that is completely obsolete with IPv6 - just assign public addresses to every system (which will never overlap) or alternatively generate random prefixes for each subnet for use in ULAs (which are long enough so that collisions are very unlikely).
Thanks. This is so usefl where it generate code for lot of platform.
Nice tool. One nitpick:
When I try to use my scroll wheel to scroll down to the bottom so I can see the whole diagram, it zooms out instead of scrolling. For some reason it disproportionately annoys me when sites hijack scroll events to do something other than scroll.
