# 1. WildCard Records

To manage subdomains in YunoHost/Coolify/Dokploy or any other container management software with integrated reverse proxy you can send all subdomain request all to the same IP address. This allows you adding each one to Cloudflare, you can create a <span class="font-semibold" data-streamdown="strong">wildcard DNS record</span>. This means adding a wildcard A record (e.g., `*.yourdomain.com`) that points to your server's IP address, allowing any subdomain to resolve without additional configuration.
