A Records (Address Records) are the foundation of your domain’s DNS zone. They link a domain name to a specific IP address, telling the internet where to find your website or other services.
For example:
- When someone visits your-domain.com, the A record directs them to the IP address of your web server where your website files are hosted.
- You can also use A records for services like email, e.g., pointing mail.your-domain.com to the IP address of your mail server.
A Records are also commonly used alongside MX Records to help direct emails correctly.
In short, A Records define where traffic to your domain or subdomain should go.
