Sid Sub Sweep

Sid Sub Sweep (3S) is a free IPv4 network utility for subnet discovery, individual host ping and spreadsheet-friendly CSV exports. Review your Wi-Fi IPv4 subnet using its actual CIDR mask, or enter an authorized target, and start a bounded ICMP sweep. Only responding devices appear in the list and export. Green dots mean a device answered ICMP. No ICMP response does not prove a device is offline. Scan progress and cancellation keep you in control. Ping a Host accepts an IPv4 address or fully qualified hostname. Hostname queries use the operating system’s configured DNS resolver and may leave your device. One resolved IPv4 address is selected and pinned for the run. On iOS, Your network defaults to a usable en0 Wi-Fi interface and displays available local IP and subnet information. Unsupported gateway, DHCP and DNS details are hidden. Device names and peer MAC addresses are unavailable on iOS; missing values display blank in the device list. Export responding results as CSV with IP address, device name and MAC-address columns. The native share menu lets you choose where to save or send the file. Sharing can transfer the export outside your device. XLSX export and IPv6 probing are not included. Subnet sweeps support /22–/32, up to 1,022 addresses. Results stay in memory until you explicitly export or share them. There is no developer cloud backend, account, advertising SDK, analytics or subscription. Optional links open externally only when tapped. Use diagnostics only on networks and hosts you are authorized to test.
