l8nc
Multi-target continuous ping monitor. Pings your gateway, ISP hop, and public DNS simultaneously, showing a live braille chart so you can instantly see where your internet is breaking.
Built for network engineers who need quick answers during calls.
Install
PyPI (recommended)
pip install l8nc
Or with pipx for an isolated install:
pipx install l8nc
Homebrew (macOS/Linux)

brew install l8nc
Usage
# Auto-detect gateway, ISP hop, and public DNS
l8nc
# Add custom targets to defaults
l8nc 10.0.0.1 example.com
# Only ping specified targets (skip auto-detection)
l8nc --only 10.0.0.1 example.com
# Limit to 10 pings
l8nc -c 10
# Save per-target CSV logs
l8nc -l logs/
# Replay chart from saved logs
l8nc --replay logs/
What it does
l8nc auto-discovers three network hops and pings them in parallel:
- Gateway — your local router
- ISP hop — first hop outside your network (via traceroute)
- Public DNS — Google (8.8.8.8) and Cloudflare (1.1.1.1)
All targets overlay on a single live chart. Timeouts show as [NO REPLY] rather than 0ms spikes, so the chart stays useful.
