This wasn't the most useful on its own, only ensuring that forward and reverse DNS entries match each other (you'll be shocked by how many places it isn't!) - and we need a good way to simplify DNS administration with …

In a previous post I covered how to deploy vSphere VMs with Ansible and the Automation …

VMware's PowerCLI is a fantastic tool, but it's not for me. Tweaking or porting functionality from PowerCLI to other …
