DNS Lookup
Inspect your domain's public DNS records and configuration.
DNS records are the public phone book for your domain — they tell the internet where your website lives, which servers handle your email, and who's authorized to speak for your brand. A misconfigured record can mean mail silently bouncing, a stale server nobody uses anymore, or an attacker's server quietly authorized alongside yours. This tool reads exactly what the public internet sees today, with no login and no changes made.
