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 Trace Context specification defines standard HTTP headers and a value format for propagating context information that enables distributed tracing.
