# NetPing Network diagnostic tool: ping hosts, scan ports, traceroute, DNS lookup, latency measurement, and HTTP checks — all in one script. ## Commands | Command | Description | |---------|-------------| | `netping ping <host> [count]` | Ping a host (default: 4 packets) | | `netping ports <host> <port1,port2,...>` | Check if TCP ports are open | | `netping trace <host>` | Traceroute to host | | `netping dns <domain>` | DNS lookup (A, AAAA, MX, NS, TXT records) | | `netping latency <host>` | Measure average latency (5 pings with stats) | | `netping http <url>` | Check HTTP status and response timing | | `netping sweep <subnet>` | Quick ping sweep of a /24 subnet | | `netping version` | Show version | ## Examples ```bash netping ping google.com # → ping with 4 packets netping ping 8.8.8.8 10 # → ping with 10 packets netping ports example.com 80,443,8080 # → check 3 ports netping trace cloudflare.com # → traceroute netping dns github.com # → A, AAAA, MX, NS, TXT records netping latency 1.1.1.1 # → avg latency over 5 pings netping http [Technical Reference] # → HTTP status + TTFB netping sweep 192.168.1.0/24 # → find alive hosts ``` ## Requirements - `ping` (standard) - `dig` or `nslookup` (for DNS lookups) - `traceroute` or `tracepath` (for trace, optional — falls back to ping TTL) - `curl` (for HTTP checks) - Bash `/dev/tcp` (for port scanning — built into bash)
