What is a DNS lookup?
A DNS lookup queries the Domain Name System to retrieve all public records associated with a domain. It translates human-readable names like github.com into IP addresses, mail servers, and configuration records used by the internet.
Debug email issues
Check MX and TXT records to diagnose delivery failures or SPF/DKIM problems.
Verify DNS propagation
Confirm that recent DNS changes have propagated across the internet.
Audit nameservers
Inspect NS records to verify your domain is pointed to the right DNS provider.
Check SSL certificates
View CAA records to see which certificate authorities can issue SSL certs.
