LANScanner
Utilities
Free
LAN Scanner helps you instantly discover every device on your local network. With a single tap, it identifies phones, laptops, TVs, printers, NAS, and IoT devices—showing IP, hostname, MAC address,
and manufacturer. It uses modern discovery (Bonjour/mDNS, SSDP/UPnP) to surface friendly names so you know exactly what’s online.
- One‑Tap Scan: Discovers devices on your current Wi‑Fi or Ethernet network fast.
- Smart Names: Uses Bonjour/mDNS and SSDP/UPnP to show human‑readable device names.
- Vendor Lookup: Infers manufacturer from MAC addresses for quick identification.
- Live Results: See devices appear in real time as the scan progresses.
- Cross‑Platform: Built for iPhone, iPad, and Mac with native SwiftUI.
- Lightweight: No accounts, no ads, no clutter—just the info you need.

Lightweight: No accounts, no ads, no clutter—just the info you need.
-
Private by Design: All scanning and identification happens entirely on‑device. LAN Scanner never collects, uploads, or shares your network data.
-
Great For:
- Troubleshooting “what’s on my network?”
- Finding printers, TVs, and smart home devices
- Auditing small office/home networks
- Verifying new devices and guests
-
Notes: Some networks (guest/VLAN/campus) may restrict discovery. Ensure Local Network access is granted for best results.
Requirements: Local Network permission. Multicast networking improves Bonjour/SSDP discovery on supported devices.
Enhanced UI Design
- Redesigned device list with perfectly aligned column headers for IP, Hostname, Vendor, and MAC address
- Improved tap targets - easily sort by any column with a single tap
- Real-time updates - device information appears automatically as it's discovered, no more manual refreshing needed
- Vendor information now displayed inline for quick device identification
Dramatically Improved Performance
- 4x faster device discovery - now finds all network devices in seconds, not minutes
- Completely rewritten scanning engine using ARP table lookup on macOS for instant device detection
- Optimized TCP-based detection on iOS for maximum compatibility
- Progressive enrichment system resolves hostnames 20x faster with intelligent timeouts
- Parallel processing ensures smooth, responsive UI even during intensive scans
More Reliable Device Detection
- Now consistently finds 140+ devices on large networks (previously missed 50%+ of devices)
- Proper TCP RST packet detection - no longer misses devices with closed ports
- Sequential IP scanning eliminates gaps in dense DHCP ranges
- Smart concurrency management prevents network congestion and timeouts
Bug Fixes
- Fixed UI not updating automatically when MAC addresses and vendor info are resolved
- Eliminated progress bar freezing at 95%
- Resolved batch device appearance issues
- Fixed equality checking to ensure SwiftUI detects all device property changes
