Release 2026.6.4: Interactive Column Sorting, Live Countdowns, & Concurrency / Proxy ARP Fixes 🚀🕸️⏱️

Welcome to Release 2026.6.4 of the Switch Dashboard! This release introduces critical scanner optimizations, interactive column sorting, real-time sync countdown timers across all dynamic pages, and highly requested concurrency options for network discovery.

🌟 What's New in v2026.6.4

1. 🔀 Interactive Column Sorting (Subnet Scanner)

  • Multi-Type Sorting: Added interactive sorting (ascending/descending) on all scanner columns.
    • IP Addresses: Scans are sorted numerically by octets.
    • Status: Sorted alphabetically (ONLINE/OFFLINE).
    • Dates & Times: Sorted chronologically (First Seen, Last Seen Online, Last Updated).
    • Alphanumeric: Natural sort order (case-insensitive) for Hostnames, MACs, Vendors, and Notes.
  • Visual Indicators: Clickable headers render arrow indicators (▲/▼) next to the active sorting column.
  • Drag Protection: Header clicks are ignored if the user is currently resizing columns.

2. 🛡️ Proxy ARP / VPN IP Overwrite Protection & Deletion Reset

  • Proxy ARP Override Guard: Prevents multi-IP MAC addresses (such as Fritz!Box gateways responding for local virtual WireGuard VPN tunnels) from overwriting the primary IP address (like .1 for the router).
  • Ascending Scan Priority: Scanned host IPs are ordered numerically before insertion, guaranteeing that lower/primary IPs are processed first.
  • Clean Deletion Reset: Deleting a client host sets scanner_detected = False. Upon the next network scan, the scanner performs a fresh resolution to the primary gateway IP, ignoring subsequent VPN alias responses (like .200 or .201) as long as the primary IP is reachable.

3. ⚙️ Discovery Concurrency & Timeout Customization

  • Parallel Host and Port Scanning: Implemented a multi-threaded host scanner pool (scanner_host_scan_threads) using a ThreadPoolExecutor to scan multiple hosts concurrently. Ports are also scanned concurrently per-host (scanner_port_scan_threads).
  • Configurable Timeout (ms): Added a custom millisecond timeout setting (scanner_port_scan_timeout_ms, default 500 ms) for TCP port checks, allowing fast port scans.
  • Web UI Controls: Added Host/Port Concurrency and Timeout parameters directly to the settings page /config.

4. ⏱️ Live Auto-Refresh Countdowns & Smart Pausing

  • Seconds Countdown: Replaced static status labels with active 1-second interval countdown timers (e.g. Live (update in 25s)) on the Dashboard, Network Scanner, and Network Map.
  • Smart Pausing:
    • Dashboard/Scanner: Polling and countdowns pause and show Paused while editing note/nickname input cells to prevent updates from overwriting user typing.
    • Network Map: Displays a header status dot and countdown. The countdown pauses automatically if the user focuses on sidebar search or inspect detail input/selectors.
  • Strict Syncing: Routed all AJAX fetches directly through the 1-second countdown clock, ensuring perfect alignment.

5. 🎨 Styling Alignment & API Overhaul

  • Dark Mode Scrollbars: Integrated custom dark scrollbars and native dark browser settings (color-scheme: dark) in /scanner/history to match dashboard styles.
  • API Reference Overhaul: Documented all missing endpoints (Scanner, Clients, System Logs, and Topology) in the interactive /api-docs interface.
