Question 1

Why does my domain show no MX records?

Accepted Answer

If a domain has no MX records, mail servers cannot deliver email to it. This is normal for domains that are not configured for email. If you recently set up MX records and they are not showing up, DNS propagation can take up to 48 hours, though it usually completes within a few minutes.

Question 2

What is the difference between a CNAME and an A record?

Accepted Answer

An A record maps a domain directly to an IP address. A CNAME maps a domain to another domain name, which then resolves to an IP address via its own A record. Use A records when you know the IP address. Use CNAME when you want to point to another domain that might change its IP address.

Question 3

Can I check DNS records for any domain?

Accepted Answer

Yes. DNS records are public information: anyone can look them up for any domain. This is by design, as the entire DNS system relies on this transparency to route traffic correctly across the internet.
