Cloudflare DNS Records, Proxy Status, and Routing Basics
Understand Cloudflare's DNS management, proxy feature (orange cloud), and its impact on website performance and security.
Cloudflare serves as a leading global CDN and DNS service provider, offering performance optimization and security enhancements for websites. Understanding its DNS record management and proxy features is crucial for leveraging its full capabilities.
DNS Record Types: Within the Cloudflare dashboard, users can manage various essential DNS records, including:
- A Records: Map a domain name to an IPv4 address.
- CNAME Records: Point one domain or subdomain to another domain name.
- MX Records: Specify mail exchange servers for email delivery.
- TXT Records: Store text information, commonly used for SPF, DKIM, or domain verification.
Proxy Status (Orange Cloud): A core feature of Cloudflare is its proxy service. When the cloud icon next to a DNS record is orange, it indicates that traffic for that record is being proxied through Cloudflare's global network. This means visitor requests do not directly hit your origin server's IP address but are routed through Cloudflare first.
Benefits of Proxying:
- Origin IP Obscurity: Enhances security by shielding your server's direct IP from public exposure, mitigating direct DDoS attacks.
- Performance Enhancement: Leverages Cloudflare's CDN to cache content, significantly speeding up website loading times.
- Security Features: Provides Web Application Firewall (WAF) and advanced DDoS protection.
When the cloud icon is grey, traffic bypasses Cloudflare's network and directly connects to your origin server. Knowing when to enable or disable proxying is vital for website performance, security, and troubleshooting.
