What are DNS records?

DNS records are instructions that live on authoritative DNS servers and provide information about a domain including IP address (A records), mail server (MX records), nameservers (NS records), and more. They act as a directory that tells the internet how to route requests for a domain.

How often should I check my DNS records?

It's recommended to check your DNS records at least monthly, or immediately after making any changes to your domain's configuration. Regular checks help ensure your website and email services are functioning correctly and can prevent potential issues before they affect your users.

What are the most important DNS record types?

The most critical DNS record types include: A records (IPv4 addresses), AAAA records (IPv6 addresses), MX records (mail servers), NS records (nameservers), CNAME records (domain aliases), and TXT records (text information including SPF records). Each serves a specific purpose in your domain's configuration.

How do I fix common DNS issues?

To fix common DNS issues: 1) Verify your DNS records are correctly configured, 2) Ensure your nameservers are properly set at your domain registrar, 3) Check that your A records point to the correct IP addresses, 4) Confirm MX records are properly set for email delivery, 5) Allow sufficient time for DNS propagation after making changes.

Why is DNS propagation important?

DNS propagation is the time it takes for DNS changes to spread across all DNS servers worldwide. This process can take 24-48 hours because DNS servers cache information to improve performance. During propagation, some users might see old DNS records while others see updated ones.

DNS propagation is crucial because:

It's the time needed for DNS changes to spread worldwide
Can take 24-48 hours to complete
DNS servers cache information to improve performance
During propagation, users might see different versions of DNS records

Always allow sufficient propagation time when making DNS changes.
