Bulk DNS Records Lookup 🌐 — A, AAAA, MX, TXT, NS, CNAME, SOA & CAA (No API Key)

Look up DNS records for thousands of domains in a single run. This bulk DNS lookup tool queries every domain you give it for the record types you choose — A, AAAA, MX, NS, TXT, CNAME, SOA, CAA — over DNS-over-HTTPS and returns a clean, one-row-per-record table with values, TTLs and the resolver that answered. No API key, no local resolver, no rate-limit headaches, no login.

🏆 Why this bulk DNS lookup?

8 record types · thousands of domains per run · one clean row per record · DNS-over-HTTPS with automatic failover · export to JSON / CSV / Excel. The free bulk DNS lookup API alternative (no key) for email deliverability, security audits and DNS migrations — an MX record checker, SPF / DMARC TXT lookup, nameserver lookup and CAA audit in one tool.

✨ What this Actor does / Key features

• 🌐 Bulk lookups — resolve thousands of domains in a single run, in parallel.
• 🧩 8 record types — A, AAAA, MX, NS, TXT, CNAME, SOA, CAA — pick any subset or query them all.
• 📄 One row per record — every A address, every MX host and every TXT entry gets its own row for easy filtering and export.
• 🔐 DNS-over-HTTPS — uses Cloudflare dns-query as the primary resolver with an automatic Google fallback; no local DNS resolver needed and it works from cloud environments where UDP DNS is blocked.
• 🧹 Clean values — TXT chunks are joined into one string, trailing dots trimmed, MX priorities preserved (e.g. 10 smtp.google.com).
• ⏱️ TTL captured — every record includes its TTL in seconds, exactly as returned by the resolver.
• 🧪 Robust input parsing — https://, paths, ports and trailing dots are stripped automatically; duplicates removed.
• 🛟 Graceful on NXDOMAIN / empty — missing records simply produce no rows; the run never crashes on non-existent or empty answers.
• ⚡ High concurrency — configurable parallel lookups (default 10, up to 100) for very large lists.
• 🔑 No API key — works out of the box against public DNS-over-HTTPS endpoints.

🚀 Quick start (3 steps)

1. Configure — paste your list of domains into Domains (one per line; bare example.com or full https://example.com/path both work) and pick the Record Types you want.
2. Run — click Start. The Actor resolves every domain in parallel over DNS-over-HTTPS and streams one row per record into your dataset.
3. Get your data — open the Output tab and export to JSON, CSV, Excel or XML, or pull it via the Apify API. Sort/filter by recordType.

📥 Input

Give the Actor at least a domains list. Everything else is optional.

Example — full DNS audit across a domain portfolio

{
  "domains": ["google.com", "github.com", "cloudflare.com"],
  "recordTypes": ["A", "AAAA", "MX", "NS", "TXT", "CNAME", "SOA", "CAA"],
  "maxConcurrency": 10,
  "proxyConfiguration": { "useApifyProxy": true }
}

Example — email deliverability check (MX + SPF/DKIM/DMARC only)

{
  "domains": ["acme.com", "example.org", "mail.startup.io"],
  "recordTypes": ["MX", "TXT"],
  "maxConcurrency": 20
}

Example — high-volume nameserver + CAA inventory

{
  "domains": ["site1.com", "site2.com", "site3.com"],
  "recordTypes": ["NS", "CAA"],
  "maxConcurrency": 50,
  "proxyConfiguration": { "useApifyProxy": true }
}

Field	Type	Description
domains	array	Domains / hostnames to look up. Schemes and paths are stripped automatically — example.com and https://example.com/path both work. Required.
recordTypes	array	Which record types to query for every domain: any subset of A, AAAA, MX, NS, TXT, CNAME, SOA, CAA. Default: all 8.
maxConcurrency	integer	Parallel DNS-over-HTTPS lookups. Higher is faster. Default 10, max 100.
proxyConfiguration	object	Proxy used for the lookups. Recommended (Apify datacenter proxy by default) to avoid resolver rate limiting at scale.

Tip: Provide bare domains (example.com) for the cleanest results; subdomains (mail.example.com) work too. Select only the record types you need to keep runs lean — or all 8 for a complete DNS audit.

📤 Output

One row per DNS record — exportable to JSON, CSV, Excel or XML. A domain with several A addresses, multiple MX hosts and a handful of TXT entries can easily yield 15–30 rows on its own. Here is a trimmed sample:

[
  { "domain": "google.com", "recordType": "A", "value": "142.250.190.78", "ttl": 300, "resolver": "cloudflare", "checkedAt": "2026-07-06T18:00:00.000Z" },
  { "domain": "google.com", "recordType": "MX", "value": "10 smtp.google.com", "ttl": 3600, "resolver": "cloudflare", "checkedAt": "2026-07-06T18:00:00.000Z" },
  { "domain": "google.com", "recordType": "TXT", "value": "v=spf1 include:_spf.google.com ~all", "ttl": 3600, "resolver": "cloudflare", "checkedAt": "2026-07-06T18:00:00.000Z" },
  { "domain": "github.com", "recordType": "NS", "value": "dns1.p08.nsone.net", "ttl": 86400, "resolver": "cloudflare", "checkedAt": "2026-07-06T18:00:00.000Z" },
  { "domain": "cloudflare.com", "recordType": "CAA", "value": "0 issue \"digicert.com\"", "ttl": 1800, "resolver": "google", "checkedAt": "2026-07-06T18:00:00.000Z" }
]

💡 Use cases

• Email deliverability — pull MX and TXT across a domain portfolio to verify mail routing and valid SPF / DKIM / DMARC policies before a campaign.
• Security & compliance audits — inventory CAA (allowed certificate authorities), NS delegation and mail routing across many domains at once.
• Infra & DNS migrations — snapshot every record type before a hosting or DNS-provider cutover, run again after, and diff the datasets to confirm clean propagation.
• Change monitoring — schedule recurring runs on a cron and detect when records change over time.
• Due diligence / OSINT — map infrastructure (A, AAAA, CNAME) and enrich large domain lists with live DNS metadata.

👥 Who uses it

Email / deliverability teams & ESPs · security engineers & pentesters · SREs & DevOps running DNS migrations · IT & compliance auditors · OSINT & threat-intel analysts · domain portfolio managers · growth & lead-gen teams enriching domain lists.

💰 Pricing

This Actor runs on a simple pay-per-result model — you pay for the records you resolve, with no separate Apify platform fees to calculate. The public DNS-over-HTTPS endpoints are free. Try it on the free tier first, then scale up. See the Pricing tab on this page for the current rate.

❓ Frequently Asked Questions

Is it legal to look up DNS records in bulk? Yes. DNS records are public infrastructure metadata answered by public resolvers. This Actor only queries publicly available DNS data; you remain responsible for using the results in line with applicable laws.

Is there a public DNS API — and is this a free DNS lookup API without a key? There's no single official DNS API you need to sign up for. This Actor queries public DNS-over-HTTPS endpoints (Cloudflare, with a Google fallback), so it acts as a free bulk DNS lookup API alternative — you just provide a list of domains and run, then read results from the dataset or the REST API. No key to manage.

Do I need an API key or a login? No. There is no key, token or login required — only an Apify account. It works out of the box against public DoH resolvers.

How do I look up DNS records for many domains at once? Paste your full list of domains into the Domains field and run the Actor once. It resolves every domain in parallel over DNS-over-HTTPS and returns one row per record, so a single run can cover thousands of domains.

Can I check MX records in bulk? Yes — select MX (alone or with other types) and the Actor returns every mail server and its priority for each domain, e.g. 10 smtp.google.com. It works as a dedicated bulk MX record checker across your whole list.

How do I find SPF / DKIM / DMARC records? Include TXT in the record types. SPF, DKIM and DMARC policies all live in TXT records, and this Actor pulls them for every domain — a fast SPF / DMARC checker and TXT record lookup at scale.

How do I audit CAA records across many domains? Include CAA and run your domain list once; the Actor lists which certificate authorities are allowed to issue certs for each domain over DNS-over-HTTPS.

How do I export DNS records to CSV or JSON? Every lookup is one row, so the dataset drops straight into a spreadsheet. Download it as CSV, JSON or Excel, or pull it through the REST API.

How much data can I get? There's no fixed cap — a few hundred domains across all 8 record types quickly become thousands of rows. Increase maxConcurrency and keep the proxy enabled for very large lists.

What happens with a non-existent domain (NXDOMAIN)? The lookup completes cleanly and simply produces no rows for that domain/type. The run never crashes on missing or empty records.

Why DNS-over-HTTPS instead of normal DNS? DoH works reliably from cloud environments where UDP DNS is often blocked, returns structured JSON, and pairs cleanly with Apify Proxy to avoid resolver rate limits at high volume.
