About This Tool
A DNS lookup queries the Domain Name System to find the records attached to a domain, most commonly the A record that maps a name to an IPv4 address. DNS is the internet's directory: it translates human-readable names such as example.com into the numeric addresses machines route by.
Beyond A records, a lookup can reveal AAAA records for IPv6, MX records that direct email, CNAME aliases, TXT records used for verification and policy, and NS records that name the authoritative servers. Checking these helps diagnose why a site or mail service is not resolving as expected, or confirm that a recent change has propagated.
DNS changes do not take effect everywhere at once: records are cached for a period set by their time-to-live, so a freshly updated record may still resolve to the old value from cached copies until that timer expires. Checking a lookup against the authoritative name servers shows the intended value before caches catch up.
