In my last post, we created a DNS zone and added a record pointing back to the public IP address of my home broadband connection.

That's all well and good, but since it's not a static IP, it can of course change - so we want to be able to keep the record up to date with the current IP.

Today I'll show you one way of doing that, using a very lightweight updater client (windows or linux) that uses an Azure PowerShell function (ok, I might be a bit of a fanboy when it comes to those!) to update the DNS record-set entry.

The more that I use Azure cloud services, the more I think of ways to use them, either to do something new, or to replace some process or service I already use.

Today, I'll show you how you can use Azure DNS to provide a Dynamic DNS capability at significantly reduced cost compared to services like No-IP and DynDNS. A future post will automate the process of keeping the DNS entry up-to-date.
