About Codynet
What this is
Codynet is a free network toolbox: DNS, RDAP, HTTP headers, TLS certificates, subnet math, multi-resolver compare, and bulk lookups. No accounts. No paywall. No upsell.
Why it exists
Most lookup sites bury the answer under ads, log every query you make, or wrap public protocols in their own proprietary APIs. Codynet talks DNS straight to a resolver, RDAP straight to the registry, and TLS straight to the server you ask about. No middleman, no rebranded data.
What we believe
- Determinism over decoration. Show the protocol’s real answer, with the real flags, TTLs, and error codes. If the resolver said
SERVFAIL, that’s what you see. - Privacy by structure. Your lookup history lives in your browser, not on our server. Server logs never contain query content. There is nothing to leak because nothing is collected.
- No vendor lock-in. Every result panel includes the equivalent
digorcurlcommand so you can verify the answer outside our site.
Who’s behind it
Codynet is built and maintained by Cody, a network enthusiast.
