I am using Enom.com's DNS Servers to manage several domains' DNS settings. I'm having trouble understanding how to correctly set up the DNS so that all http requests will resolve to a naked domain without resulting in
example.com redirected you too many times error.
So, regardless of any of the following:
http://www.example.com http://foo.example.com http://*.example.com
The DNS record should always redirect to the naked domain of
IIS Server (Windows 2016)
Further, I'd prefer not to set up an IIS URL Rewrite with a Canonical Domain Name rule for every domain. My preference is to have the DNS records simply resolve everything back to the naked domain.
IIS Host Records
My server relies heavily on Host Header Records to correctly resolve the incoming request to the correct website. In other words, several domains' A Records point to the same IP Address on my server.
Current DNS Record Configuration (with Enom)
Host Name Record Type Address www URL Redirect example.com @ (none) A (Address) 22.214.171.124 * (all others) URL Redirect example.com
The URL Redirect record is a special record Enom provides. From the Enom Host Records help page:
URL Redirect is not a native DNS record type. Specifying URL Redirect for a hostname creates an underlying A record that directs the name to our URL Forwarding servers. These servers then perform an HTTP 301 redirect to the URL you specify in the address field. You can specify only the domain name to go to, or a full path to a specific file.
Summary of Question
How can I set up the DNS Records so that all variants of a domain are always sent to the naked domain without having to use an IIS URL Rewrite rule?
