## 16 Network Tools in One App

### Connectivity Tools

- **Ping:** Test host reachability with ICMP or HTTP HEAD. See per-packet latency, packet loss, and round-trip statistics. When ICMP is blocked by a firewall, switch to HTTP HEAD with one tap.
- **HTTP(S) Check:** Verify URL reachability, view status codes, response timing, redirect chains, and a quick TLS summary.
- **Traceroute:** Visualize the hop-by-hop path your traffic takes to any destination. Identify where latency spikes or packet loss occurs.
- **Speed & Latency Baseline:** Get a quick snapshot of latency, jitter, and download/upload throughput on your current connection.
- **TCP/UDP Connect:** Test whether a specific host and port combination is reachable, with connection timing and clear error reasons.
- **Wake-on-LAN Sender:** Send magic packets to power on compatible devices across your local network.

### Lookup Tools

- **WHOIS:** Look up domain registration details, registrar info, nameservers, and lifecycle events using RDAP (with automatic WHOIS fallback).
- **DNS Lookup:** Resolve hostnames using system or custom DNS servers.
- **DNS Record Explorer:** Query A, AAAA, CNAME, MX, TXT, NS, and SRV records with full TTL display.
- **TLS Certificate Inspector:** Examine certificate expiry dates, Subject Alternative Names (SANs), the full issuer chain, and weak-certificate signals.
- **Public IP + Geo/ASN:** Instantly see your public IP address, ISP, ASN, and approximate geolocation.

### Scanning Tools

- **Port Scan:** Check TCP port reachability across custom port ranges.
- **LAN Scan:** Sweep your local subnet to discover active hosts.
- **Subnet Calculator:** Compute CIDR details, usable host ranges, broadcast addresses, and gateway suggestions for both IPv4 and IPv6.
- **Bonjour Browser:** Discover .local network services like AirPlay, HomeKit, printers, and more using mDNS.
- **UPnP / NAT-PMP Discovery:** Detect local gateway mapping support and external IP hints.

## Save Hosts and Work Faster

NetDebug Toolkit isn't just a collection of one-off tools. Its Saved Hosts feature lets you store domains, IP addresses, and MAC addresses that you frequently diagnose. Select a saved host, and every relevant tool is pre-filled and ready to run.

- Save hosts by domain/IP or MAC address
- Add optional display names for quick identification
- Automatic duplicate prevention
- Host-scoped tool lists that filter based on host type (MAC address hosts automatically surface Wake-on-LAN)
