Bulk Domain WHOIS & DNS Lookup

Check hundreds of domains in one run. For each domain you get the registrar, registration and expiry dates, DNS records, email security (SPF and DMARC), and SSL certificate expiry. Paste a list, click Start, and download a spreadsheet.

The Actor uses RDAP, the official successor to WHOIS that registries now run. It returns clean, structured dates instead of messy WHOIS text.

What you get for each domain

• Registration: registered or available, registrar, created, updated, and expiry dates
• Expiry alerts: days until the domain expires, and domain age in days
• Status: registry status codes such as transfer or delete locks, plus DNSSEC
• DNS records: A, AAAA, MX, NS, TXT, CNAME, SOA, and CAA
• Email security: the SPF record, the DMARC record, and the DMARC policy (none, quarantine, or reject)
• SSL certificate: valid or not, issuer, expiry date, and days until expiry
• Quick flags: has a website, accepts email

Common uses

• Domain portfolio monitoring: catch domains and SSL certificates before they expire
• IT and security audits: find domains missing DMARC or SPF, or with a weak p=none policy
• Agency onboarding: see a new client's registrar, DNS host, and mail setup in one table
• Lead and market research: check domain age and whether a site and mailbox exist
• Availability checks: see which names on a list are unregistered

How to use it

1. Paste domains or full URLs into Domains, one per line.
2. Leave Check SSL certificate on, or turn it off for a faster run.
3. Click Start. Open the "Domains" table, or export JSON, CSV, or Excel.

Run it on a schedule to get a weekly expiry report.

Pricing

You pay per domain looked up, with no monthly fee. Duplicates are removed first, and Max domains caps your cost.

Notes

• Data comes from public registry RDAP servers and public DNS. Some registries hide registrant contact details for privacy. This Actor does not collect personal contact data.
• A few country-code registries do not offer RDAP yet. For those, you still get DNS, email security, and SSL data, and rdapError explains what was missing.
