## What it is
Networking Toolbox is a collection of 100+ free, open-source networking utilities for system administrators and network engineers, covering DNS lookups, subnetting, TLS/HTTP analysis, and IP tools. It runs offline-first in the browser, offers a free API, and can be self-hosted via Docker.

## Use cases
- calculate ipv4 and ipv6 subnets and cidr ranges
- check dns propagation and validate spf dkim dmarc records
- analyze tls certificates and security headers of a website
- look up asn, bgp routes, and ip geolocation
- convert mac address formats and find the vendor from oui
- test dns resolver performance across providers
- self-host a suite of offline networking utilities
- generate dhcp option 43 for wireless controller discovery

## When to choose
- you need a quick, free, no-signup toolbox for common network diagnostics
- you want offline-capable tools that work without sending data to third parties
- you're a sysadmin or network engineer doing dns, subnetting, or tls analysis regularly
- you want to self-host networking utilities on your own server via docker

## When to avoid
- you need deep packet capture or traffic analysis (use Wireshark instead)
- you require continuous network monitoring and alerting rather than on-demand checks
- you need programmatic automation at scale beyond the provided API
- you need GUI-based network mapping or topology discovery tools
