DNS Lookup
Query A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV and CAA records for any domain - bounded to a 3s timeout.
DNS records control how a domain name resolves - which server it points to, how email is routed, and more. This tool queries all the common DNS record types (A, AAAA, CNAME, MX, TXT, NS, SOA, PTR, SRV, CAA) for any domain, useful for debugging domain configuration, verifying DNS changes have propagated, or investigating how a domain is set up.
Frequently asked questions
A records point a domain to an IPv4 address. AAAA records point to an IPv6 address - modern domains often have both to support visitors on either type of network.
They specify which mail servers handle email for a domain, and in what priority order - essential for verifying email is routed to the correct provider (like Google Workspace or a custom mail server).
DNS changes take time to propagate globally due to caching (TTL - time to live) at various points across the internet - it can take anywhere from minutes to 24-48 hours depending on the record's TTL setting and caching along the way.
