I’ve been building my infrastructure in my homelab with Terraform for a while now, one thing that has always been a pain is finding an IP address that’s not in use and then creating a DNS record in pfSense. To solve the IP address problem I’ve decided to use Netbox. This will allow me to plan out the layout of the network and get available IPs using the API. I’ve decided the first step to address this is to create a Terraform module, this will simplify the code.
