IP Subnet Network vs Network Scanner Toolkit

IP Subnet Calculator. Subnet Mask Converter and Invertor

See every device on your WiFi. Free — no ads, no subscription. Now on iPad and built for iPhone Duo. Network Scanner Toolkit finds everything on your network in seconds: name, IP, MAC address and manufacturer (iOS 27+) — even devices that hide from ping. Devices tell you what they are: Apple TV, HomePod, Chromecast, printers, HomeKit and Matter gear, Sonos, Fire TV, Windows PCs, NAS boxes and more. Capability tags show which are pingable, run a web interface, speak Bonjour, UPnP or Matter, or are your gateway. Filter by Web UI, SSH, file shares, printers, TVs, smart home or cameras. Tap a device to ping it, open its admin page, connect over SSH, VNC or SMB, rename or favorite it. New devices are flagged automatically. Made for big screens. On iPad and the iPhone Duo the scanner becomes three columns — past scans, device list and full details side by side — and the tools spread into two panes. Stand the Duo up like a laptop and every tool splits across the hinge: graph, map or results on top, controls below. Fold, unfold or rotate and nothing is lost. A full network toolbox — free: • LAN Scanner — fast sweep with naming over Bonjour, NetBIOS, WS-Discovery and SNMP; models and manufacturers, custom names & icons, new-device badges, filters, quick-connect. Scans Wi-Fi, Personal Hotspot or wired, and keeps going after you leave the app (iOS 26+). • Subnet Tools — IPv4 and IPv6. Type any address with a prefix, netmask or wildcard and get the whole answer on one card: network, broadcast, host range, counts, type with its RFC, binary with host bits highlighted. Then explore: child subnets on a visual map, VLSM planner, overlap checker, supernet, membership test, range-to-CIDR, config lines, IPv6 forms, netmask table.
