🆚 DNS Prefetch vs. RelMeAuth

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.

RelMeAuth is a proposed open standard for using rel-me links to profiles on OAuth supporting services to authenticate via either those profiles or your own site.
