Handling Internationalized Domain Names in a Globalized Internet

The internet, as a global medium, has transcended linguistic and cultural boundaries, connecting billions of people from diverse regions and languages. However, its foundational infrastructure, including the Domain Name System (DNS), was originally designed with a limited character set based on ASCII, which primarily supports the English alphabet, numbers, and a few symbols. As the…

Network Management in the Era of Encrypted DNS Traffic

The Domain Name System, or DNS, has long been a cornerstone of internet functionality, providing the mechanism by which human-readable domain names are resolved into machine-readable IP addresses. For much of its history, DNS queries were transmitted in plaintext, offering no confidentiality or integrity protections. While this simplicity facilitated broad compatibility and ease of implementation,…
