What is a DNS lookup?
DNS (Domain Name System) is the internet's phonebook. When you type a domain like netspaceindia.com into your browser, DNS translates it to the IP address of the server that hosts the site. A DNS lookup is the process of asking a DNS resolver for the records attached to a domain.
Different DNS record types answer different questions. An A record tells you the IPv4 address, MX records tell you which servers accept email, TXT records carry verification data like SPF, DKIM and DMARC. Our free tools make it easy to inspect any of these for any public domain — useful when you're configuring hosting, debugging email delivery, verifying domain ownership, or checking that a DNS change has propagated.
