Domain Intelligence: WHOIS + DNS Bulk Lookup

Pass a list of domains. Get back WHOIS, DNS records, and inferred signals per domain in one row each. Built for sales prospecting, brand protection, and email deliverability audits.

Use it to

• Segment a cold outbound list by email platform (Google Workspace vs Microsoft 365)
• Audit DMARC and SPF posture across your customer or partner list
• Check WHOIS expiry dates on a domain portfolio
• Identify the DNS provider (Cloudflare, Route 53, Azure, GoDaddy) for tech-stack research

Who this is for

Role	What you use it for
SDR / outbound rep	Segment your prospect list by email platform. Different cold email templates for Google Workspace vs Microsoft 365 inboxes.
Brand protection team	Bulk audit registrar, expiry dates, and unauthorized lookalike registrations across a domain portfolio.
Email deliverability consultant	Check SPF and DMARC posture across a client's entire customer base.
Sales engineer	Identify the DNS or hosting provider on a target account list to tailor pitches.
Security analyst	Inventory MX and DMARC records across an organization's owned domains.

---

Pricing vs typical alternatives

Tool	Effective price per lookup
WhoisXML API	$0.01 to $0.04
Whoxy	$0.0009 (cheap but slow, no DNS, no signals)
MXToolbox	$9 a month, capped at 1,000 lookups
This actor	$0.005 with first 10 free per run

You get WHOIS, DNS, and the inferred signals layer in one call. Most alternatives charge separately for each.

Inferred signals reference

Email provider is inferred from MX records. Supported labels: Google Workspace, Microsoft 365, GoDaddy Email, Zoho Mail, Proton Mail, Rackspace, Amazon SES, SendGrid, Mailgun, Proofpoint, McAfee MX, Mimecast, Fastmail, Yandex Mail.

DNS provider is inferred from NS records. Supported labels: Cloudflare, AWS Route 53, Google, Azure DNS, NS1, DNSimple, DNS Made Easy, GoDaddy, Namecheap, Network Solutions, DigitalOcean, Hurricane Electric.

If no rule matches, the signal is null and the raw records are still in the row.

Input fields

Field	Type	Default	Notes
domains	array of strings	required	Plain domains or full URLs. Up to 10,000 per run.
includeWhois	boolean	true	RDAP lookup for registrar and dates.
includeDns	boolean	true	A, MX, NS, TXT records.
includeDmarc	boolean	true	DMARC TXT lookup at _dmarc.<domain>.

What this actor does NOT do (yet)

• Subdomain enumeration. Input is root domains only.
• HTTPS certificate inspection. TLS chain and expiry are out of scope. Pair with a TLS scanner for that.
• Reverse WHOIS lookups. No "find all domains owned by Org X" queries.
• WHOIS history snapshots. v1 returns the current record. Historical data is not available via RDAP.

---

Cross sell

Pair this actor with:

• Lead Enrichment Pipeline for domain to contacts, then segment by email platform from this actor
• Website Content Crawler for full text content per domain
• GitHub Issue Monitor for tech-team activity on target accounts

Compliance posture

WHOIS via RDAP and DNS records are public registry data, designed for programmatic access. No authentication or scraping bypasses are involved. Personal data in WHOIS records is redacted by registries per GDPR for individual registrants and is not surfaced by this actor.
