## What it is
A Docker image packed with network troubleshooting tools (tcpdump, nsenter, dig, curl, and more) designed to be attached to any container, host, or Kubernetes pod's network namespace. It enables non-destructive debugging of containerized environments without installing tools into production images.

## Use cases
- debug network issues in a docker container without installing tools
- troubleshoot dns resolution failures in kubernetes pods
- capture packets from a running container with tcpdump
- inspect a pod's network namespace with an ephemeral debug container
- debug host networking without installing anything on the host
- run a throwaway network debugging pod in kubernetes

## When to choose
- you need to diagnose connectivity, DNS, or routing problems inside containers or Kubernetes pods
- you cannot or should not modify the target image or install packages on the host
- you want a single preloaded image with dozens of network tools ready to go

## When to avoid
- you need persistent monitoring rather than interactive debugging
- your environment forbids privileged containers or host network access
- you only need basic tools already present in your base image
