HTTP Redirection of zone apex

Often you need to redirect all traffic from the domain apex, also known as the naked domain or domain root. 
Ususally you need to make all visitors to http://yourdomain.com to automatically go to www.yourdomain.com. 
Luckily, Dyn has a service that does just that, without getting all of the redundant traffic to your web servers. 

To start, log into your Dyn account, and select the domain to modify. 
Switch your your view to "Simple Editor".

You should be seeing your SOA records and NS records. 

If your naked domain is already pointing to an A record, delete it. DO NOT PUBLISH YET. 

Below the list of records, there is a drop down titled "Add a New Service".  Select the HTTP Redirect service. 

Publish to commit the change to the Dyn servers.
