🔎 DNS Records Lookup — Bulk A, MX, CNAME, TXT, NS, SPF & DMARC at Scale

Resolve DNS records — A, AAAA, MX, CNAME, NS, TXT, SOA, CAA, SPF, DMARC — for thousands of domains in one run. A drop-in alternative to MXToolbox ($129-$999/yr), Constellix, NS1, Pingdom, and dnschecker.org — without per-seat fees or single-domain UIs.

Why This Actor Beats MXToolbox, dnschecker.org, Constellix & Pingdom

Feature	NexGenData DNS Records Lookup	MXToolbox	dnschecker.org	Constellix	Pingdom
Cost	$2 per 1,000 lookups, pay-per-event	$129 - $999 / year	Free (UI, ad-supported)	$4 - enterprise / month	$10 - $90+ / month
Bulk lookup	Unlimited CSV / JSON / Excel	Limited per plan	Single domain	API on paid tiers	Monitor-style
Record types	A, AAAA, MX, CNAME, NS, TXT, SOA, CAA, SPF, DMARC	Same	Same	Same	Selected
Auth	Apify token	Account + plan	None	Account	Account
Time-to-first-row	< 60 seconds	Plan signup	Browser only	Plan signup	Plan signup
Output	Clean JSON / CSV / Excel	UI export	UI / CSV	API JSON	UI / API
Multi-resolver	Apify-managed (Google + Cloudflare + 1.1.1.1)	Selected resolvers	12+ global resolvers	Own anycast	Own monitors
Schedule + webhook	Native	Plan-gated	None	API only	Plan-gated

Most security + ops teams pick this actor because it is cheaper than MXToolbox's annual subscription and the only way to bulk-lookup 10,000 domains worth of MX / SPF / DMARC records in a single CSV.

What You Get

For each domain, fields include:

• A / AAAA records (IPv4 + IPv6 addresses)
• MX records with priority + mail-server hostname
• NS records (authoritative name servers)
• CNAME chain (where present)
• TXT records (raw + parsed SPF / DKIM / Google verification / etc.)
• SOA record (primary NS, admin contact, serial, refresh / retry / expire / minTTL)
• CAA records (certificate-authority authorization)
• SPF parsed mechanisms (include / a / mx / ip4 / ip6 / ~all / -all)
• DMARC parsed policy (p, sp, pct, rua, ruf, aspf, adkim)
• Resolution timestamp + resolver used

Output flows to a clean Apify dataset — export as CSV / JSON / Excel or hit the dataset REST API.

Use Cases

• Email-deliverability audits — verify SPF / DKIM / DMARC for every domain a client owns
• Security ops — confirm MX records haven't been tampered with across a portfolio of brand domains
• M&A due-diligence — audit DNS hygiene of an acquisition target's domain set
• Sales enablement — enrich a B2B prospect list with hosting / email infrastructure for outbound
• DevOps migration prep — bulk verify cutover NS changes propagated across your fleet
• Phishing investigation — pull MX + SPF + DMARC for suspicious lookalike domains
• Hosting market research — measure which CDNs / DNS providers dominate a vertical
• Compliance — periodic DNS-record snapshots for SOC 2 / PCI evidence trails

Quick Start

from apify_client import ApifyClient
client = ApifyClient("YOUR_APIFY_TOKEN")
run = client.actor("nexgendata/dns-records-lookup").call(run_input={
    "domains": ["example.com", "openai.com", "anthropic.com"],
    "recordTypes": ["A", "MX", "TXT", "NS", "SPF", "DMARC"]
})
for item in client.dataset(run["defaultDatasetId"]).iterate_items():
    print(item["domain"], item["MX"], item["DMARC"])

Pricing

Pay-per-event — no monthly minimum:

• Actor Start: ~$0.0002 per run
• Result: $0.002 per domain resolved

Examples:

• 100 domains ≈ $0.20
• 1,000 domains ≈ $2
• 10,000 domains ≈ $20
• 100,000 domains / month ≈ $200

Compare to MXToolbox Delivery Center starting at $129/yr capped at ~1,000 lookups — this actor handles 10,000 domains for ~15% of the annual cost.

FAQ

Q: Which resolver does this use? Multi-resolver — internally rotates between Google (8.8.8.8), Cloudflare (1.1.1.1), and Quad9 (9.9.9.9). The chosen resolver is captured per-record.

Q: Is this rate-limited? Apify auto-scales the actor. Resolution itself is bottlenecked by DNS authoritative servers, not by us. Tens of thousands of domains per hour are routine.

Q: Does it follow CNAME chains? Yes — full chain captured, plus the final A / AAAA target.

Q: Can it detect missing SPF / DMARC? Yes — missing records return null so you can filter for domains with weak email security.

Q: How fresh is the data? Live — each lookup hits the authoritative DNS at request time. No caching beyond the platform's brief in-run cache for repeated queries.

Q: Can I run this on a daily schedule? Yes — built-in Apify Schedules with cron + webhook on dataset write.

Q: Does it handle IDN (internationalized domains)? Yes — pass either the Unicode or punycode form; the actor returns both.

How NexGenData Pricing Works

Every NexGenData actor uses pay-per-event pricing — you only pay for results that actually land in your dataset. No monthly minimum, no seat fees, no surprise overage bills.

• Actor Start: a single-event charge each time you spin the actor up (scaled to memory size)
• Result: charged per item written to the default dataset
• No charge for retries, internal proxy rotation, or failed sub-requests — those are absorbed by the platform

If you only need the data once a quarter, you only pay once a quarter. If you scale to millions of records, the unit cost stays the same.
