Bulk DNS Lookup & DNS Change Monitor

Get A, AAAA, MX, NS, TXT, CNAME, SOA, CAA (and SRV/PTR) records for thousands of domains via public DNS-over-HTTPS resolvers, with no login, no browser and no code. Export to JSON, CSV or Excel, or use the API.

Resolve A, AAAA, MX, NS, TXT, CNAME, SOA, CAA (and SRV/PTR) records for thousands of domains via public DNS-over-HTTPS resolvers. Detects DNS host and email provider (Cloudflare, Route 53, Google Workspace, Microsoft 365...), SPF/DMARC, site-verification tokens, and in monitor mode reports added/removed records.

Use cases

• Lead qualification: who uses Google Workspace vs Microsoft 365, Cloudflare, etc.
• Watch your own or clients' domains for unexpected DNS changes (hijack/misconfig alerts)
• Migration audits and bulk MX/SPF checks

Input

domains	array	Domains or URLs.
recordTypes	array	Any of A, AAAA, MX, NS, TXT, CNAME, SOA, CAA, SRV, PTR.

Pricing

Pay per result, with no monthly rental or subscription:

• Domain resolved: $0.001
• DNS changed (monitor): $0.005

Example: 1,000 results cost about $1.00 in fees. Apify's free plan includes $5 of monthly credit, which is enough to test this Actor.

FAQ

Do I need an account, cookies or a login for the source site? No. Bulk DNS Lookup & DNS Change Monitor uses public data sources only, so there is nothing to connect and no account to risk.

How much will a run cost? You pay only for results delivered (see Pricing above), plus Apify platform usage, which the free plan's monthly credit easily covers for test runs. Start with a small limit to see the exact cost per run.

Can I export to CSV, Excel or Google Sheets? Yes. Every run's dataset can be downloaded as JSON, CSV, Excel, XML or HTML, or pushed to Google Sheets, Make, Zapier, n8n, Slack or a webhook through Apify integrations.

Can I run it on a schedule or from my own code? Yes. Add an Apify Schedule (hourly, daily, weekly) or call it through the Apify API / Python & JavaScript clients. It also works with AI agents through the Apify MCP server.

What happens if an input is invalid or a source is down? The run keeps going. The bad input gets a row with an error field so you can see what failed, and you are not charged for results that were not delivered.

Is this legal to use? It collects publicly available data. You are responsible for using the output in line with the source's terms and privacy laws such as GDPR/CCPA; don't use it for spam.

Something missing or broken? Open an issue on the Issues tab. Feature requests are usually added within a few days.

Scheduling / monitoring

Create a Schedule (daily/weekly) and connect a webhook or Slack/email integration.

Fair use

Official public APIs only, no login. Do not use output for spam or harassment. Respect the data sources' rate limits and terms.
