Bulk DNS Lookup

Check DNS records for multiple domains at once with our bulk lookup tool. Query A, MX, TXT, and NS records in batch operations.

ReviewMyDNS is a free DNS propagation checker that queries 50+ global DNS servers to verify your DNS records. Check A, AAAA, MX, CNAME, TXT, NS, and SOA records instantly.

When Single Lookups Are Not Enough

Most DNS tools are built for checking one domain at a time. That works fine for troubleshooting a single site, but it's impractical when you need to audit DNS records across dozens or hundreds of domains simultaneously. The ReviewMyDNS bulk lookup tool accepts a list of domains and runs the same DNS query against all of them in parallel, returning a consolidated results table you can scan or export.

Common Use Cases

  • Post-migration audit: After moving a portfolio of domains to a new DNS provider, run a bulk A record check to verify all domains are resolving to the correct IP. A single missed domain can mean a site is silently pointing to the old server.
  • Email deliverability audit: Check MX and TXT records for all domains in your organisation. Identify which domains are missing SPF, DKIM, or DMARC records before they cause delivery failures or get your IP ranges blacklisted.
  • Nameserver migration verification: After changing nameservers for multiple domains, run a bulk NS lookup to confirm each domain has delegated to the correct nameservers and propagation is complete.
  • Client domain health checks: Agencies and MSPs managing multiple client domains can run periodic bulk checks to surface misconfigurations before clients notice problems.
  • Propagation monitoring during cutover: When migrating multiple sites simultaneously, use bulk A record lookups to monitor propagation progress across the entire batch rather than checking each domain individually.

How to Use Bulk Lookup

Paste your list of domains (one per line) into the input field, select the DNS record type to query (A, AAAA, MX, TXT, CNAME, NS, or SOA), and submit. The tool returns the current DNS response for each domain in a table. Inconsistent results across a list of domains that should all resolve to the same value immediately highlight which domains were missed or are still propagating.

Bulk Lookup vs. DNS Monitoring

Bulk lookup is a point-in-time snapshot — it tells you what DNS looks like right now across a list of domains. For ongoing change detection, use DNS monitoring, which watches your records continuously and alerts you when values change unexpectedly.
