🌐 DNS Propagation Checker

Check DNS propagation across 8 global resolvers (Google, Cloudflare, Quad9, OpenDNS). Detect inconsistencies after DNS changes.

Store Quickstart

Start with the Quickstart template (3 domains, A records). For multi-record audits, use Full DNS Audit (A, AAAA, MX, TXT, CNAME, NS).

Key Features

• 🌐 8 global DNS resolvers — Google, Cloudflare, Quad9, OpenDNS, Cisco Umbrella, Level3, Verisign, Dyn
• 📋 7 record types — A, AAAA, MX, TXT, CNAME, NS, SOA
• ⚠️ Inconsistency detection — Instantly spots resolvers that disagree
• ⏱️ TTL reporting — See caching behavior across resolvers
• 📦 Bulk domains — Check up to 200 domains per run
• 🔑 No API key needed — Uses Node.js built-in dns.Resolver

Use Cases

Who	Why
DNS administrators	Verify DNS changes propagated globally before changing URLs
Hosting migrations	Confirm nameserver switch completed at all resolvers
Email deliverability	Check MX, SPF, DKIM TXT records consistency
Security teams	Detect DNS hijacking via inconsistent resolver responses
DevOps teams	Pre-deploy DNS verification for production cutover

Input

Field	Type	Default	Description
domains	string[]	(required)	Domains to check (max 200)
recordTypes	string[]	["A"]	A, AAAA, MX, TXT, CNAME, NS, SOA

Input Example

{
  "domains": ["example.com", "api.example.com"],
  "recordTypes": ["A", "MX", "TXT"]
}

Output Example

{
  "domain": "example.com",
  "recordType": "A",
  "resolvers": [
    {"name": "Google", "ip": "8.8.8.8", "values": ["93.184.216.34"], "ttl": 86400},
    {"name": "Cloudflare", "ip": "1.1.1.1", "values": ["93.184.216.34"], "ttl": 86400}
  ],
  "isConsistent": true,
  "inconsistencies": []

FAQ

Why use 8 resolvers?

DNS caching varies by resolver. Checking multiple reveals which have updated after a change.

What's a typical propagation time?

TTL-dependent. Most DNS changes propagate globally within 1-24 hours.

Does it check geographic propagation?

No — all resolvers queried are major public ones. For geographic checks, use specialized tools.

Can I check private DNS?

No, only public DNS. Internal/private domains return NXDOMAIN.
