Getting started

DR-NetTools is a professional networking diagnostics suite for Android, iOS, Desktop (Windows, macOS, Linux) and Android TV. Everything a field tech, sysadmin or network engineer needs for a quick check: ping, traceroute, MTR, DNS, port and host scans, WHOIS, GeoIP, SSL inspection, Wi-Fi analysis, IPv4/IPv6 calculators, iperf3 speed tests, Wake-on-LAN, a built-in SSH client and more.

The sidebar

On Desktop and tablets a sidebar lists all tools grouped by function. On phones the same list opens from the hamburger icon. Groups are colour-coded:

• Analyze — ping, traceroute, MTR, port scan, DNS, rDNS, WHOIS, GeoIP, SSL, Wake-on-LAN, SSH, speed test, DNS propagation, Bonjour/mDNS.
• Discover — Wi-Fi scan, Wi-Fi channels, network map, hosts in range, host monitor.
• Calculators — IPv4 subnet, IPv6 address, IPv6 subnet splitter.
• Other — Main dashboard, Settings, About, Licences.

The Main screen at the top of the list shows a summary of the device's network state: active interfaces with IPv4/IPv6 addresses, public IP, routing table, connectivity and airplane-mode status. It's the first thing to glance at when something feels off.

Running your first ping

1. Sidebar → Ping.
2. Type a hostname or IP (1.1.1.1, 8.8.8.8, github.com, or an IPv6 like 2606:4700:4700::1111).
3. Press Start. Echo replies stream in as they arrive, a live RTT graph builds up and the average is displayed above the list.
4. Press Stop to cancel. Clear wipes the buffer.

Packet size, timeout and other global defaults live in Settings — the same values apply to every pinging tool (Ping, Host monitor, Network map, Hosts in range).

The results view pattern

Most tools share a common pinned top bar with three actions next to the title — reused across the app:

• Start / Stop — the big button drives the tool. The bar turns into a progress indicator while work is running.
• Share — sends the current results out via the system share sheet (Android/iOS) or opens the save dialog (Desktop). Format is plain text — paste into a ticket, email, Markdown doc.
• Copy — long-press any value in a result list to copy it to the clipboard. The same long-press on an address opens a menu with Copy, Use in… (jump to Ping, Traceroute, WHOIS, GeoIP, SSL, DNS, calculators) and platform-specific actions.

Tapping the title in the top bar toggles a short description of the tool — useful for first-time visits, out of the way afterwards.

Saved hosts and groups

The Host monitor screen doubles as your saved-hosts book. Create groups (e.g. Home, Office, Servers), add hosts to each, and the app periodically checks reachability with a coloured status chip: green for reachable, red for unreachable, grey for unknown/cancelled.

• Add group — name it and it appears in the list, collapsible.
• Add host — hostname or IP, any address BaseAddress accepts.
• Ping group / Ping all — one-shot check; last response time is remembered.
• Tap a host — opens the context menu to ping it, copy the address, or jump into any other tool with the address pre-filled.

The free tier caps the total number of saved hosts (across all groups). A PRO upgrade removes the limit — see Settings & platforms.

Where to go next

• Diagnostics — Ping, Traceroute, MTR, DNS, rDNS — everyday troubleshooting.
• Scanning — Port scanner, Bonjour/mDNS, Network map, Host monitor — discovery on a LAN.
• Lookups — WHOIS, GeoIP, SSL/TLS, DNS propagation — external / public-data queries.
• Wi-Fi — SSID scan and channel analyser.
• Calculators — IPv4/IPv6 subnetting.
• Utilities — Speed test, Wake-on-LAN, SSH.
• Settings & platforms — configuration, permissions, platform differences, licensing.
