Check live DNS records for any domain, including A, AAAA, MX, TXT, NS, CNAME, SOA, CAA, SPF, DMARC, and DKIM-related signals.
DNS controls where a domain sends website traffic, email, verification records, and many third-party services. When DNS is wrong, a website may fail to load, email may bounce, SSL may not validate, or marketing tools may not verify ownership. This DNS lookup tool gives you a quick way to inspect public records before making hosting changes, domain migrations, email updates, or launch decisions.
Use this tool to confirm A records, AAAA records, CNAME aliases, MX mail routing, TXT verification records, SPF, DMARC, nameservers, SOA details, and CAA certificate rules. It is useful before moving a site to a new host, connecting Cloudflare, setting up Microsoft 365 or Google Workspace, troubleshooting email delivery, checking domain propagation, or verifying that a client domain points to the right server.
After reviewing DNS, check SSL status, HTTP headers, redirects, page size, and website speed. DNS can look correct while HTTPS, caching, mail authentication, or redirects still need work. For a full launch review, combine this DNS Lookup Tool with the SSL Certificate Checker, Redirect Checker, HTTP Headers Inspector, and Website Speed Test.
