Can't configure external DNS for a custom domain

Support

I’m going to Netlify App and trying the following from the docs:

“In the Custom domains panel, select Check DNS configuration next to the custom domain to open customized details about the DNS records you need to configure. The instructions will vary depending on the type of domain or subdomain.”
(Configure external DNS for a custom domain | Netlify Docs)

I don’t see Check DNS configuration in the Custom domains panel. Is there any other way to do this?

Thanks.

Hi, @rainshadedesign, and welcome to our Netlify community site. :+1:

The “Check DNS configuration” option only appears if the required DNS records are not working.

Note, for the www subdomain, this isn’t configured as recommended. That is currently an A record:

www.NOT-REAL.net. 3600	IN	A	104.198.14.52

Using the load balancer IP address is only recommended for apex/root domains and, even then, only if ALIAS records for the apex/root domain are not supported.

The www subdomain record should be a CNAME record pointing to the netlify.com subdomain for this Netlify site. For example:

www.NOT-REAL.net. 3600	IN	CNAME	confident-saha-7b4f0a.netlify.com.

So, it is working but it isn’t using our CDN nodes around the world to improve site performance. Making the change to a CNAME will correct this.

​Please let us know if there are other questions about this.
