A Records

When do I use an A record?

A records are ideal for pointing your domain (or subdomain) at a server that has a static (does not change) IP address.

This is frequently the case when you want to point your domain (like “example.com”, or subdomain (like, “www.example.com”) to a server where your website is hosted, if your web host provides you with an IP address of the server where your content is stored (hosted).

Can I have an example?

Here is a model that you can follow:

www 10800 IN A 123.123.123.123

You will need to replace www with the name of the subdomain you want, and 123.123.123.123 in the above example with the IP address that your provider gives you.

As a reminder, * means “every subdomain”, so if you have an * A record, then there is no need for www unless you want to override the IP address you gave with your * entry.

If you want just the domain, then you need the @ record you see in the above example, or:

@ 10800 IN A 123.123.123.123

Usually both the * and @ are used, but one or the other (or both) will only work if the server hosting your website are configured for the particular address.
