ZDNS expert enters the decision - making level of the world's top management institution for IP addresses

From November 9th to 14th, at the ICANN81 meeting, Ma Di, a member of the NRO NC (also a member of the ICANN ASO) and the chief researcher of the National Engineering Research Center for Internet Domain Name System (ZDNS), participated in the meeting. He communicated with the global Internet community about the revision of the governance policies for Internet numbering resources, providing support for the global distribution and management of IPv6 addresses and AS numbers in the future.

01 ZDNS Expert Provides Suggestions for Global IP Address Resource Allocation

The Number Resource Organization (NRO) is one of the core institutions of the global Internet governance system. It is responsible for coordinating and allocating the IPv4 addresses, IPv6 addresses, and autonomous system numbers required for the operation of the global Internet. Representing five international Internet address registration agencies, including the Asia-Pacific Network Information Centre (APNIC), the American Registry for Internet Numbers (ARIN), the Réseaux IP Européens Network Coordination Centre (RIPE NCC), the Latin American and Caribbean Internet Addresses Registry (LACNIC), and the African Network Information Centre (AFRINIC), it jointly participates in global Internet governance to ensure the fair distribution of IPv6 addresses and related digital resources and support the stable and reliable operation of the global Internet.

Ma Di, the chief researcher of the National Engineering Research Center for Internet Domain Name System (ZDNS), was elected as a member of the NRO NC in 2021. He participates in the global allocation and management of resources such as IPv6 addresses, provides suggestions, and participates in decision - making to promote the fair and reasonable distribution of IPv6 addresses worldwide.

02 Participating in the Formulation of International and Domestic Industry Standards

ZDNS focuses on basic resource fields such as domain names and IP addresses. Through the research and development of next - generation DNS technology, it leads innovation in areas such as IPv6 dynamic address allocation, unique IPv6 domain name identification, and IPv6 integration and transition, and contributes to international standards.

ZDNS has led the formulation of three technical requirements for the Resource Public Key Infrastructure (RPKI) of Internet IP address resources, namely RFC8211, RFC8416, and RFC8897. This is conducive to better achieving the two deployments of "upgrading the security system" and "strengthening address management" for IPv6 - oriented network routing control.

On October 9th, 2024, experts from China Telecom, Tsinghua University, the National Engineering Research Center for Internet Domain Name System (ZDNS), and the Asia - Pacific Network Information Centre (APNIC) jointly drafted the "Configuration File for Mapping Origin Authorization (MOA)". They proposed the MOA technology under RPKI to verify the authenticity of the address mapping rule information transmitted by BGP in an IPv6 - only network, ensuring the accurate transmission of IPv4 service data in an IPv6 - only network.

ZDNS has participated in the formulation of domestic communication industry standards, such as "Technical Requirements for IPv6 Network Domain Name Service" (YD/T 2139 - 2010) and "Technical Requirements for IPv6 Address Coding and Management - Address Lease Query Based on DHCPv6" (YD/T 3065 - 2016), etc. These efforts promote the large - scale deployment of IPv6 and support the comprehensive upgrade of digital infrastructure to IPv6.

Since its establishment, the National Engineering Research Center for Internet Domain Name System (ZDNS) has actively participated in the international Internet governance community, contributing Chinese wisdom to building a more open, secure, and orderly cyberspace. By giving play to its technological research and development advantages, it innovates in IPv6 address allocation and IPv6 address management products, integrates with industry needs to support the large - scale deployment of IPv6, and builds a solid network foundation for the in - depth advancement of the integration of the digital and real economies.
