Bulk DNS Lookup

Check many domains at once and export the results to CSV.

● Runs in your browser
Record types
Two record types that trip people up: PTR only works on IP addresses — put an IP on a line and it is converted to in-addr.arpa for you. SRV and TLSA always live under a sub-name, so enter the full name, e.g. _sip._tcp.example.com. Many types across many domains means many queries — progress is shown next to the button.

How it works

The same DoH queries as DNS Lookup, looped over every domain × record type you select. The table and the CSV file are built in your browser.
