DNS records are entries in the DNS database that provide information about a domain. Common types include A records (IPv4 addresses), AAAA (IPv6), MX (mail servers), CNAME (aliases), TXT (text information like SPF), and NS (nameservers).
DNS propagation typically takes 24-48 hours to complete globally, though many changes propagate within a few hours. The time depends on TTL (Time To Live) values and how DNS servers cache records.
MX records determine where email for your domain is delivered. Checking MX records helps troubleshoot email delivery issues and verify that your mail servers are correctly configured.
