Mapping a custom naked domain to your Azure Website, a URL with no www

  • Article

This article has been moved to its new home here: https://benperk.github.io/waws/2014/2014-10-mapping-a-custom-naked-domain-to-your-azure-website-a-url-with-no-www.html

A naked URL means that there is no www before the domain name and domain extension.  For example, https://www.benjamin.perkins.me which I use often to troubleshoot and experiment with mapping custom domains to my Azure Web App.  An example of how to do map a custom domain is provided here, and would more than likely result in your naked domain (https://benjamin-perkins.me) working.  However, if some configuration gets skipped or mixed up, you might need these instructions too.

The key point is that you must have an A Record that points to the IP address provided via the Microsoft Azure management portal.  For example, that shown in Figure 1.

Note that the IP address is 137.135…., this is the value you need to set you’re a Record to.

Before I could enter benjamin-perkins.me into the Manage custom domain section I needed to add a CNAME as mentioned in Figure 1.  I logged into my DNS providers web site and made the addition as shown in Figure 2.  Note that for this example, I am binding the custom domain to an Azure Web App named IISLOGS.

Once that was added and after it propagated, I was able to add the custom naked domain to my Azure Web App, as shown in Figure 3.

Next step was to then add the A Record using my DNS providers’ web site, as shown in Figure 4.

Once the A Record propagates then accessing https://benjamin-perkins.me will work.  During this configuration testing, it did take some time for the A Record to propagate.  I used NSLOOKUP to check what IP address was linked to it.  Once I saw that the NSLOOKUP resulted showing the 137.135.* IP address, it worked as expected, as shown in Figure 5.
