What Is a DNS Lookup?
A DNS lookup is a query that asks the Domain Name System which records a domain publishes — such as A/AAAA (IP addresses), MX (mail servers), NS (authoritative name servers), and TXT (verification/SPF/DKIM). It’s used to troubleshoot routing, email delivery, and domain ownership verification.
