About Lookup DNS Now

Overview

Purpose

Lookup DNS Now is a free browser utility published by SBFChoice for quick public DNS checks.

It uses DNS-over-HTTPS (JSON) instead of a terminal dig command so you can verify records from any device.

For production incidents, compare answers from more than one resolver and confirm changes at your DNS host.
