nwtools.org is a practical network tools website for DNS, email, IP, web, TLS,
and security checks. The goal is simple: help you reach the right check quickly,
understand the result, and know what to do next.
The site is designed for direct tool use, not content filler. Each page is meant
to work as a utility page first, with clear inputs, readable output, and strong
next-step guidance.
What you can use here
You can use nwtools.org to check DNS records, nameservers, propagation, email
authentication records, IP details, reachability, web responses, TLS certificate
data, security headers, blacklist signals, and related troubleshooting paths.
How the site is built
The frontend is built as a fast Astro site with lightweight client-side behavior.
Some checks use live public DNS lookups, and some advanced checks use a backend
helper where browser-only access would be incomplete or misleading.
Where a tool has limitations, the page should say so directly instead of
overpromising what the result means.
