This tool is being set up. Backend processing coming soon. In the meantime, review the reference guide below and use the CLI equivalent.
Bulk Domain Checking: Use Cases
1. Server migration audits: Moving dozens of client sites to a new server? Check DNS and SSL for all domains to verify the migration completed successfully.
2. Portfolio health monitoring: Hosting providers and agencies can bulk-check all client domains weekly to catch expiring certificates and misconfigured DNS before clients notice.
3. Competitor analysis: Check where competitors host their sites (DNS provider, IP ranges) and what SSL setup they use — in bulk.
4. Domain portfolio cleanup: Check which domains still resolve, which have expired certificates, and which are parked — decide what to renew and what to drop.
Input Format
Paste domains one per line, or comma/space separated. Up to 50 domains per check. Results include DNS A/AAAA records and SSL certificate status (issuer, expiry, days remaining).
CLI Equivalent
while read d; do echo "$d: $(dig +short $d A)"; done < domains.txt
