CIDRGen Changelog

2026-10-31 — Moved onto the shared template; calculator rebuilt; three tools added

• The site now renders through the same template as the other tools: tools hub, embeddable widget, generated privacy and terms pages.
• Fixed: the "Sample: /24" button did nothing (its handler was written with nested double quotes). It works.
• Changed: the calculator used to print only host counts and a private/public label, although the page described network and broadcast addresses, ranges and wildcard masks. It now prints all of them, for IPv4 and IPv6, and validates the address instead of looking only at the prefix.
• Changed: the old private/public test was a string prefix check (startsWith("172.16.")), which called 172.20.0.0 public. It now uses real range arithmetic.
• Added: subnet splitter, CIDR overlap checker, netmask converter.
• The hand-written /cheatsheet/ page is now the guide CIDR cheat sheet, with the table recomputed from the arithmetic.
