IP Scanner & Service Watcher

IP Scanner & Service Watcher is a field toolkit for IT support engineers, network administrators, CCTV/camera technicians, and home lab users. Diagnose the network you are connected to, discover LAN devices, check open ports, inspect TLS certificates, resolve DNS, run ping/traceroute, and watch important services from your phone.

KEY FEATURES

- LAN discovery: scan the current subnet or a custom CIDR/IP range and review device IP, MAC, vendor, online/offline state, and open-port status.
- Port scanning: use focused profiles for IT, servers, network devices, and CCTV systems, or enter custom ports and ranges.
- Multi-instance tasks: run ping, LAN port checks, WAN checks, traceroute, and loop scans side by side, then jump back to each live task from the running-task badge.
- WAN visibility: detect public IPv4/IPv6 and check public port reachability through an external probe.
- Network tools: Ping, DNS Lookup, Traceroute, Website Check, Site Alive, Endpoint Health, Content Match, SSL/TLS Check, Domain Expiry, Subnet Calculator, Wake-on-LAN, and MAC vendor lookup.
- Service Watchers: convert supported tool runs into recurring checks with healthy/failing/recovered states, thresholds, cooldowns, history, and optional notifications.
- Clear diagnostics: TLS, HTTP, DNS, TCP, IPv6, and OS-level limitations are reported clearly so field work does not stop at a vague network error.

The app is designed for networks and systems you own or are authorized to test. It is not a nearby Wi-Fi/SSID scanner, Wi-Fi analyzer, wardriving tool, VPN, proxy, or broad internet scanner.

No account is required for the core scanning tools.
