About

thenetworkery.com is a free collection of network tools built by a network engineer who runs a small DN42 network (AS4242421711).

Every check explains what it found and how to fix it, gives you a link to share, and is available as a JSON API.

Privacy

No ads, no trackers, no third-party fonts or scripts. Saved results are kept for 90 days. Your IP address is stored only as a one-way hash, to stop abuse.

Fair use

The tools check one thing at a time and are rate limited. They are not for scanning networks you do not run.
