  managed_zone = google_dns_managed_zone.prod.name
  type         = "A"
  ttl          = 300

  rrdatas = ["8.8.8.8"]

Answer 1

Google Cloud DNS does not support dynamic DNS.

Google Domains does support Dynamic DNS but does provide a Terraform provider. There is a simple API that you can use.

Answer 2

Dynamic DNS allows you to direct your domain or a subdomain to a resource that is behind a gateway that has a dynamically assigned IP address. Follow this link for DNS A record with dynamic ip and also can use cloudflare to set the Dynamic IP . You can find the code in GitHub .
