Bulk DNS Lookup

Runs in your browser

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

Domains — one per line or comma separated, up to 200

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.
