DNS Lookup Tool

Note: true network-level ping and traceroute can't run from a browser for security reasons. This tool performs a real DNS lookup instead, which is the browser-safe way to check how a domain resolves.

What DNS records tell you

DNS (Domain Name System) records map a domain name to the information systems need to route traffic — like the IP address a domain points to, its mail servers, or ownership verification text. Different record types serve different purposes.

An A record maps a domain to an IPv4 address. AAAA does the same for IPv6. MX records specify mail servers. TXT records hold arbitrary text, often used for domain verification or email security (SPF/DKIM). NS records list the authoritative name servers for a domain.

Common uses

Checking DNS records is useful when setting up a new domain, verifying that a website or email is configured correctly, debugging why a domain isn't resolving, or confirming DNS changes have propagated after an update.
