Katnet vs IP Scanner & Service Watcher

katnet is a network discovery and connectivity toolkit for IT Professionals. See which hosts are online, which ports respond, and what each device advertises-then jump straight into SSH or VNC when you need a terminal or remote desktop. Discover devices Run a TCP sweep across your subnet (with a sensible default port set, or your own list). Results merge with Bonjour browsing and SSDP/UPnP-style hints so cameras, printers, NAS boxes, and servers show up with clearer context. Enrichment includes lightweight probes where appropriate (for example HTTP, TLS certificate summaries, SSH banners, and SNMP where reachable) to build a richer fingerprint-without sending your scan results to us. Built-in clients Use SSH for shell access and VNC for remote screen sharing to machines you are authorized to manage. A URL test tab helps verify HTTP/HTTPS reachability and status. A Status view summarizes local addressing and network context. Privacy katnet is built for on-network, on-device use. Discovery talks to your routers, printers, and servers over local Wi-Fi or Ethernet. You control when scanning runs. Grant Local Network access when iOS asks so multicast, Bonjour, and LAN probes can work. Important Only scan networks and systems you own or have explicit permission to test. Unauthorized scanning or access may violate law or policy.

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.
