Why D.NIX

Not just another DNS checker

Most DNS tools do one thing. D.NIX does nine — and goes deeper on each one.

9 tools in one tab

DNS Lookup, WHOIS/RDAP, IP Intelligence, DNSSEC validation, Global Propagation, Email Deliverability, CT Log monitor, Batch analysis, and Domain Compare — everything in one place, no tab-hopping.

Authoritative DNS data

We query root and authoritative nameservers directly — not third-party APIs that recycle stale data. What you see is what the internet sees right now. DNSSEC chain validation goes all the way to the root.

Live queriesDNSSEC chain200+ resolvers

Deep IP intelligence

Most tools show a city and ISP name. D.NIX shows RPKI/ROA validation, BGP upstream providers, PeeringDB IX memberships, ASN analysis across all 5 RIRs, and network allocation hierarchy. Built for engineers, not guesswork.

API Data Quality

Real-time vs. cached API responses

Understand exactly what data you get with each plan when using the REST API.

Free Plan

API responses may be served from cache (up to 1 hour old). Cached results are flagged with cached: true and a cache_note. Cached responses never count against your quota — only live lookups do.

Example API response
{
  "status": "ok",
  "meta": {
    "cached": true,
    "cache_note": "Served from cache. Upgrade for real-time.",
    "domain": "example.com"
  }
}

Pro & Enterprise

Every API call triggers a live lookup — zero stale data. DNS propagation changes are reflected immediately. Ideal for production monitoring and alerting pipelines.

Example API response
{
  "status": "ok",
  "meta": {
    "cached": false,
    "domain": "example.com",
    "rate_limit": {
      "plan": "Pro",
      "limit_per_hour": 1000,
      "remaining": 997
    }
  }
}

FAQ

Common questions

No. The Free plan requires only an email address. You'll only need payment details when upgrading to a paid plan.
Each live API or Web UI lookup counts as one request. Cached results served to guest and free-plan users are completely free — they never increment your usage counter.
To keep the service fast and affordable at scale, Free plan API calls may return results cached up to 1 hour earlier. The response always includes a cached flag. Upgrade to Pro or Enterprise for guaranteed real-time data on every call.
Yes. Upgrade at any time and your new limits take effect immediately. Downgrades take effect at the end of your current billing cycle.
The API returns 429 Too Many Requests with a Retry-After header. Your limits reset on a rolling hourly and daily window.
Yes — every tool has a corresponding endpoint: /api/v1/dns, /api/v1/whois, /api/v1/ip, /api/v1/dnssec, /api/v1/propagation, /api/v1/email, and more. Full docs at API Docs.
