DNS PrefetchType
About
The rel="dns-prefetch" attribute on 
HTML <link> elements instructs web browsers to resolve domain names for external resources before those resources are requested.
It is commonly used for third-party domains serving scripts, fonts, analytics, advertisements, or media files, helping reduce DNS lookup latency and improve loading performance for external connections.
The rel="preconnect" attribute on HTML <link> elements instructs browsers to establish early connections to external origins before resources are requested.
It is used to reduce latency by opening DNS lookup, TCP handshake, and TLS negotiation in advance for critical third-party domains such as CDNs, font providers, and analytics services.
