# Domain WHOIS & DNS Lookup - Bulk Domain Intelligence (`santamaria-automations/domain-whois-dns`) Actor Bulk domain intelligence — WHOIS records (registrar, dates, contacts), DNS records (A, MX, TXT, NS), and email provider detection. Perfect for B2B prospecting, security audits, domain monitoring, and data enrichment. - **URL**: https://apify.com/santamaria-automations/domain-whois-dns.md - **Developed by:** [Alessandro Santamaria](https://apify.com/santamaria-automations) (community) - **Categories:** Lead generation, Developer tools, Automation - **Stats:** 2 total users, 1 monthly users, 100.0% runs succeeded, NaN bookmarks - **User rating**: No ratings yet ## Pricing from $3.00 / 1,000 domain lookup completeds This Actor is paid per event. You are not charged for the Apify platform usage, but only a fixed price for specific events.

Actors are a software tools running on the Apify platform, for all kinds of web data extraction and automation use cases. In Batch mode, an Actor accepts a well-defined JSON input, performs an action which can take anything from a few seconds to a few hours, and optionally produces a well-defined JSON output, datasets with results, or files in key-value store. In Standby mode, an Actor provides a web server which can be used as a website, API, or an MCP server. Actors are written with capital "A". ## How to integrate an Actor? If asked about integration, you help developers integrate Actors into their projects. You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready. The best way to integrate Actors is as follows. In JavaScript/TypeScript projects, use official [JavaScript/TypeScript client](https://docs.apify.com/api/client/js.md): ```bash npm install apify-client ``` In Python projects, use official [Python client library](https://docs.apify.com/api/client/python.md): ```bash pip install apify-client ``` In shell scripts, use [Apify CLI](https://docs.apify.com/cli/docs.md): ````bash # MacOS / Linux curl -fsSL https://apify.com/install-cli.sh | bash # Windows irm https://apify.com/install-cli.ps1 | iex ```bash In AI frameworks, you might use the [Apify MCP server](https://docs.apify.com/platform/integrations/mcp.md). If your project is in a different language, use the [REST API](https://docs.apify.com/api/v2.md). For usage examples, see the [API](#api) section below. For more details, see Apify documentation as [Markdown index](https://docs.apify.com/llms.txt) and [Markdown full-text](https://docs.apify.com/llms-full.txt). # README ## Domain WHOIS & DNS Lookup - Bulk Domain Intelligence at $0.003 Know everything about any domain in seconds — full WHOIS, complete DNS footprint, SPF/DMARC/DKIM posture, and automatic email provider detection (Google Workspace, Microsoft 365, Zoho...). **Built for B2B prospecting, security audits and infrastructure research** — a fraction of the cost of SecurityTrails or DomainTools. ### What you get - **Full WHOIS** — registrar, creation/update/expiry dates, registrant org & country, name servers, EPP status codes, DNSSEC flag - **Age + expiry pre-calculated** — `age_days` and `days_until_expiry` ready to filter - **Complete DNS** — A, AAAA, MX, TXT, NS, CNAME, SOA in a single query - **Email security audit** — automatic SPF, DMARC and DKIM detection - **Email provider detection** — Google Workspace, Microsoft 365, Zoho, Proton, IONOS, Infomaniak and 15+ more identified from MX records - **Smart input normalization** — accepts URLs, `www.` prefixes, bare domains; deduplicates automatically - **No API keys, no setup** — paste domains and run ### Example output ```json { "domain": "apple.com", "whois": { "registrar": "CSC Corporate Domains, Inc.", "registrant_organization": "Apple Inc.", "registrant_country": "US", "created_date": "1987-02-19T05:00:00Z", "updated_date": "2024-01-25T16:54:20Z", "expires_date": "2026-02-20T05:00:00Z", "age_days": 14293, "days_until_expiry": 320, "name_servers": ["a.ns.apple.com", "b.ns.apple.com", "c.ns.apple.com", "d.ns.apple.com"], "status": ["clientTransferProhibited", "serverDeleteProhibited"], "dnssec": false }, "dns": { "a": ["17.253.144.10"], "aaaa": ["2620:149:af0::10"], "mx": [{ "priority": 10, "host": "apple.com.s.mail-aol.com" }], "txt": ["v=spf1 include:_spf.apple.com ~all"], "ns": ["a.ns.apple.com", "b.ns.apple.com"], "soa": { "primary_ns": "a.ns.apple.com", "admin_email": "hostmaster@apple.com", "serial": 2024012501 } }, "has_spf": true, "has_dmarc": true, "has_dkim": false, "email_provider": "Other / Self-hosted", "scraped_at": "2026-04-07T12:34:56Z" } ```` ### How to use Drop a list of domains (URLs work too — they're normalized automatically) into the `domains` input and run. One structured record per domain comes back with full WHOIS + DNS + email posture. #### Input | Parameter | Description | Default | |-----------|-------------|---------| | `domains` | Domains to look up (URLs auto-normalized) | *(required)* | | `includeWhois` | Perform WHOIS lookups | `true` | | `includeDNS` | Perform DNS lookups + SPF/DMARC/DKIM | `true` | | `dnsRecordTypes` | Record types to query | `["A","AAAA","MX","TXT","NS","CNAME","SOA"]` | | `useDNSServer` | DNS resolver (`host:port`) | `8.8.8.8:53` | | `timeoutSeconds` | Per-query timeout | `10` | ### Use cases - **B2B sales targeting** — identify which prospects use Google Workspace vs Microsoft 365 and tailor your pitch - **Security audits** — flag every domain missing SPF, DMARC or DKIM as a spoofing-risk finding - **Fraud & phishing detection** — low `age_days` + privacy protection is a classic phishing signal - **Due diligence** — map a target company's full DNS footprint before an M\&A deal - **Domain portfolio monitoring** — track expiry dates across thousands of domains; catch lapses before competitors do - **Competitive intel** — detect when competitors re-platform email or change DNS infrastructure - **Lead list enrichment** — append domain age, email provider and email security to scraped CRM exports ### Pricing | Event | Price | |-------|-------| | Actor start | $0.001 | | Per domain looked up | $0.003 | **Example**: Look up 10,000 domains = **$30.01** (vs SecurityTrails starter at $99/mo for limited queries) | Domains | Cost | |---------|------| | 100 | $0.30 | | 1,000 | $3.00 | | 10,000 | $30.00 | No monthly fees. No minimum spend. ### Tips - **URLs are fine** — `https://example.com/about?x=1` is normalized to `example.com` automatically - **GDPR redaction** — most registrant contact info is blank for `.com`/`.net` domains registered after 2018; the raw WHOIS text is always preserved - **Missing DMARC** — `has_dmarc: false` is one of the easiest security audit findings to flag - **Switch resolvers** — if one resolver is rate-limited, try `1.1.1.1:53` (Cloudflare) or `9.9.9.9:53` (Quad9) ### Issues & Feedback Found a bug or need an additional field?
