🆚 DNS Prefetch vs. IDN

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.

Internationalized Domain Names (IDNs) allow people around the world to use domain names in local languages, such as Arabic, Chinese, or Cyrillic.
