🎨 Beautiful Output: Color-coded RTT times show network health at a glance
📊 Multiple Export Formats: JSON, CSV, nmap, and plain text
🧠 Smart Defaults: Auto-optimizes threads, enables hostname resolution and adaptive timeout
📈 Detailed Statistics: RTT measurements, packet loss, and response time analysis
🔍 DNS Resolution: Automatic hostname lookups (disable with -n)
📁 File Input: Bulk scanning from target lists
🛡️ Interrupt Handling: Graceful Ctrl-C with automatic result saving
💻 Script-Friendly: Simple mode outputs clean IP lists for piping
⚡ Cross-Platform: Works on Linux, macOS, Windows, and ARM devices

Examples

Basic Scanning

# Simple scan with beautiful output
sudo pingr 192.168.1.0/24

# Fast scan without DNS resolution
sudo pingr -n 10.0.0.0/24

# Multiple networks
sudo pingr 192.168.1.0/24 10.0.0.0/24 172.16.0.0/24

Script Integration

# Clean IP list for piping
sudo pingr -s 192.168.1.0/24 | xargs -I {} nmap -sV {}

# Use in bash scripts
for ip in $(sudo pingr -s 192.168.1.0/24); do
    echo "Checking $ip..."
    ssh admin@$ip uptime 2>/dev/null
done

# Save to file for later processing
sudo pingr -s 192.168.1.0/24 > live_hosts.txt

Bulk Scanning

Create a targets.txt file:

# Corporate networks
192.168.1.0/24
192.168.2.0/24
10.0.0.0/24

# Branch offices
10.10.10.0/24
10.10.20.0/24

# Single servers
10.0.0.10
192.168.1.1

Then scan:

# Scan all networks from file
sudo pingr -i targets.txt

# With full features
sudo pingr -i targets.txt -t 5000 --stats -o results -f both

# Simple mode for automation
sudo pingr -s -i targets.txt > all_live_hosts.txt

Enterprise Network Audit

# Comprehensive scan with all features
sudo pingr \
    -i networks.txt \     # Read from file
    -t auto \             # Auto-optimize threads
    -c 3 \                # 3 pings per host
    --stats \             # Show RTT statistics
    -v \                  # Show all hosts
    -o audit_$(date +%Y%m%d) \  # Timestamped output
    -f both \             # JSON and text output
    --export csv          # Also export as CSV

Interrupt Handling

# Start a large scan
sudo pingr -i large_networks.txt -t 5000

# Press Ctrl-C anytime to save partial results
# Results automatically saved to pingr_interrupted_TIMESTAMP.txt/json

Understanding RTT Colors

The tool color-codes response times for quick network health assessment:

🟢 Green (0-10ms): Excellent - Local network, wired connections
🟡 Yellow (11-50ms): Good - Normal Wi-Fi, acceptable latency
🟠 Orange (51-100ms): Fair - Slower devices, potential congestion
🔴 Red (100ms+): Poor - Network issues, investigate these hosts

Performance Guide

Network Size	Hosts	Recommended Threads	Scan Time
/24	254	256	~2 sec
/22	1,022	512	~5 sec
/20	4,094	1,024	~10 sec
/16	65,534	4,096	~30 sec
/12	1,048,574	8,192	~5 min

Target File Format

The input file supports:

CIDR notation: 192.168.1.0/24
Single IPs: 10.0.0.1 (converted to /32)
Comments: Lines starting with #
Empty lines are ignored

Tips & Tricks

Speed Optimization

# Maximum speed (no DNS, high threads)
sudo pingr -n -t 10000 10.0.0.0/16

# Balanced (auto threads, with DNS)
sudo pingr 10.0.0.0/16

Network Monitoring

# Regular monitoring script
#!/bin/bash
while true; do
    sudo pingr -s 192.168.1.0/24 > /tmp/current_hosts.txt
    diff /tmp/previous_hosts.txt /tmp/current_hosts.txt
    mv /tmp/current_hosts.txt /tmp/previous_hosts.txt
    sleep 300
done

Integration with Other Tools

# Find and scan web servers
sudo pingr -s 10.0.0.0/24 | xargs -P10 -I {} curl -s -o /dev/null -w "%{http_code} {}\n" http://{}:80 2>/dev/null

# SSH availability check
sudo pingr -s 192.168.1.0/24 | parallel -j10 "nc -z -w1 {} 22 && echo {} has SSH"

# Generate Ansible inventory
echo "[servers]" > inventory.ini
sudo pingr 10.0.0.0/24 | grep -E "\.1[0-9]{2}" >> inventory.ini

Troubleshooting

Permission Denied

# Linux: Set capabilities to avoid sudo
sudo setcap cap_net_raw+ep $(which pingr)

# macOS: Always requires sudo
# Windows: Run as Administrator

No Results

Check firewall rules allow ICMP
Verify network connectivity
Try increasing timeout: --timeout 3
Some hosts may block ICMP

Slow Performance

Reduce thread count for congested networks
Use -n to skip DNS resolution
Check system ulimits: ulimit -n
