Recommended DNS setup for Multisite in the cloud

  • I have a multisite install in the cloud. Al the sites are mine. I am wondering if my DNS setup is overkill, esp as I try to migrate.

    Right now I have A records for all of them, pointing to the same IP.

    I am wondering, should I just have the main domain pointed to the IP, and the rest just have CNAME records? If the cloud provider gives me an external DNS name, should the main domain also just have a CNAME (no A record)?

    Is there a best practice here?

    CNAME is an alias. now you are using A record for direct pointing to the IP address. Don’t need to change that.

    Not sure what did you mean by “external DNS name”. Did you mean a nameserver? The main domain (almost) always an A record pointing to server IP address.
