What's New in Subnet Vault
2.4
October 1, 2026
This update makes the app faster, more reliable and easier to read. iPad: in landscape, network tool results now use the full width of the screen. VLSM calculator: the Add button now sits beside the host count field, so the keyboard no longer hides it. Very large host counts no longer crash the calculator, and a pasted network address with stray spaces is now handled correctly. Saved Results: Spotlight search now opens saved results in the right calculator. The Open button's icon is visible again, and saving the same IPv4 result twice no longer creates a duplicate. Network tools: cancelling Ping, Traceroute or WHOIS now stops it straight away. Hosts with extra spaces are accepted everywhere, and DNS lookups recover as soon as your connection returns. Auto-Detect updates right away when you join or leave Wi-Fi. Exports: VLSM CSV files now include proper subnet and wildcard masks. Accessibility: improved layout at large text sizes, better contrast, and fixes for dark mode. Plus many smaller fixes and reliability improvements.
