HostDesk

HostDesk is a powerful, lightweight network diagnostics app built for IT professionals, network engineers, system administrators, and tech enthusiasts. Whether you're troubleshooting connectivity issues, verifying DNS configurations, or scanning ports on remote servers, HostDesk gives you the tools you need — right in your pocket.
📡 Device Info
Instantly view your device's complete network configuration — WiFi IP address, MAC address, subnet mask, default gateway, SSID, link speed, signal strength (RSSI), frequency band, DNS servers in use, all active network interfaces, and your public IPv4 address.
🔁 Ping
Run ICMP reachability tests against any hostname or IP address. See live per-packet results with round-trip time, TTL, and sequence numbers. View real-time statistics including packets sent, received, packet loss percentage, and min/avg/max latency.
🔍 DNS Lookup
Perform full DNS record lookups for any domain. Retrieves A, AAAA, MX, TXT, NS, CNAME, and SOA records using a multi-strategy resolver — raw UDP DNS (port 53) with automatic fallback to DNS-over-HTTPS via Google and Cloudflare, ensuring results even on restricted networks.
🔌 TCP Port Scanner
Test TCP connectivity to any host across multiple ports simultaneously. Enter comma-separated ports or ranges (e.g. 80,443 or 1–1024). See open/closed status with response latency for each port. Includes service name identification for common ports.
📦 UDP Port Probe
Send UDP probe packets to test port reachability. Supports the same flexible port input format as the TCP scanner. Includes a clear explanation of open|filtered status behaviour specific to connectionless UDP.
🗺️ Traceroute
Discover the network path to any destination using TTL-based hop discovery via UDP.
🧮 Subnet Calculator
Full CIDR subnet analysis — enter any IP/prefix (e.g. 192.168.1.0/24) and instantly get network address, broadcast address, subnet mask, wildcard mask, first and last usable host, total and usable host count, IP class, address type (private/public/loopback/APIPA), and binary mask representation.
📋 Port Reference
Built-in reference table of 37 common TCP/UDP port assignments — from FTP and SSH to MongoDB and Elasticsearch. No internet connection required.
