Free online DNS tools: look up DNS records and domain registration, check DNS propagation around the world, test mail and DNS health, and find public and dynamic DNS services.  

Each site has quick lookups: who owns it (whois), its history (Wayback Machine), a safety check, and one-tap questions to AI helpers. Grok asks you to tap Send first.
