# sys-dns-wildcards

## Description

Create Cloudflare DNS **wildcard** A/AAAA records (`*.parent`) for **parent hosts** (hosts that have children) **and** always for the **apex** (SLD.TLD).

Examples:

- c.wiki.example.com  -> parent: wiki.example.com -> creates: `*.wiki.example.com`
- a.b.example.com     -> parent: b.example.com    -> creates: `*.b.example.com`
- example.com (apex)  -> also creates: `*.example.com`

## Overview

This role create Cloudflare wildcard DNS records (*.parent) for parent hosts; no base or*.apex records.

Solid `1:1` edges are fixed relationships; dashed `0..1` edges are conditional (enabled only in matching deployments); red `0..0` edges are turned off in this role. Node markers show the role's deploy modes (💻 host, 🐳 compose, 🐝 swarm); ❌ marks a service that is explicitly turned off, and ⚙️ an Ansible role dependency declared in `meta/main.yml`.
