DNS Portal

Multi-domain checks for DNS records, WHOIS, DNSSEC, and SPF/DMARC — centered and responsive.

Enter one per line or separate with commas/spaces. The input area is centered and won’t overflow the page.
Hold Ctrl/Cmd to select multiple. For SRV, include full name (e.g., _sip._tcp.example.com).
Note: Results use the server’s resolver. DNSSEC “Authenticated” requires a validating resolver and dig on server.
