Advanced DNS Configuration: Managing Wildcard Subdomains and Custom VPS Routing

When setting up dynamic hosting platforms or multi-tenant web applications, configuring wildcard DNS records correctly is essential. Pointing a *.yourdomain.com A record to your server's public IP allows your reverse proxy to catch dynamic subdomains on the fly.

Combined with Nginx server name matching (server_name *.yourdomain.com;), you can parse the requested subdomain dynamically in your backend application logic.

Are you managing your DNS records directly through registrars like Porkbun, or routing everything through Cloudflare for proxy protection and DDoS mitigation?
