What is it?

reconYa discovers and tracks devices on a local network. It scans IPv4 ranges using ICMP sweeps, TCP probes and ARP lookups, and identifies hosts through MAC addresses, vendor lookup, hostnames, OS fingerprints and device type classification.

Beyond discovery, it runs top-ports scans with service detection and banner grabbing in background workers, and captures screenshots of detected web services. Alerts flag new devices, risky open ports, unreachable hosts and duplicate MAC addresses, and can be acknowledged in the console. IPv6 devices are detected passively through neighbor discovery without generating traffic.

The web console provides a topology map, host list and live event log. External lookups such as public IP, geolocation and online vendor lookup are disabled by default and must be enabled explicitly.

Key features

  • 01IPv4 device discovery using ICMP, TCP probes and ARP
  • 02Passive IPv6 monitoring via neighbor discovery
  • 03MAC vendor lookup, hostname resolution and OS fingerprinting
  • 04Top-ports scanning with service detection and screenshots of web services
  • 05Acknowledgeable alerts for new devices, risky ports and duplicate MACs
  • 06Web console with topology map, host list and event log
  • 07Multiple networks with independent CIDR ranges

Use cases

  • Inventorying devices on a home or office network
  • Spotting unexpected or unidentified hosts on a LAN
  • Monitoring newly opened ports on internal machines
  • Keeping track of IPv6 devices alongside IPv4 ones
