SKULLCHECK TOOL

Bulk DNS Lookup

Query multiple public domains and multiple DNS record types in one run. Designed for quick infrastructure reviews and migrations.

Maximum 20 unique public domains per run.
Select one or more record types.
Queries run in small batches to protect the service. Results depend on DNS propagation and the resolver available to this hosting server.
BULK DNS

Compare DNS across many domains

Use this tool to review address, canonical-name, mail, nameserver, SOA, TXT and CAA records across a group of domains without opening a separate lookup for each one. For deeper SPF, DKIM and DMARC analysis, use the dedicated SkullCheck analyzers.
