On April 8, 2025, the Russian Internet Governance Forum (RIGF) hosted its traditional educational day. This event has long been a hallmark of RIGF, during which speakers and experts engage with students and young professionals across multiple cities, delivering lectures on diverse topics related to internet governance, infrastructure, cybersecurity, and international collaboration in the field.
As part of RIGF 2025’s educational day, Pavel Khramtsov — Head of DNS Projects at MSK-IX, Scientific Supervisor of Educational Projects at the Indata Foundation for the Development of Network Technologies, and 2025 laureate of the Virtuti Interneti (For Merit in the Internet Sphere) Award — delivered a lecture at Moscow Technical University of Communications and Informatics (MTUCI) on the architecture of modern internet infrastructure.
During his presentation, Khramtsov elucidated the Domain Name System (DNS) hierarchy, the role of local DNS root servers in bolstering the reliability of national root zone nodes, and shared practical case studies illustrating the implementation of DNS solutions within Russian corporate and academic networks. He also outlined contemporary trends and challenges confronting global internet infrastructure.
“A local DNS root is not merely a technical measure but a critical strategic tool for improving the efficiency and security of internet operations. It reduces access latency to authoritative servers and optimizes traffic routing, which is particularly vital for corporate and national DNS systems. Leveraging anycast technology and deploying local DNS root nodes at internet service providers unlocks new opportunities to enhance service quality and ensure network stability,” Khramtsov emphasized.
Students had the opportunity to ask questions and discuss the topic within a professional setting. For many attendees, the lecture provided valuable insights into the workings of the global technical internet and the processes behind the simple act of typing a web address into a browser.
