A New L-Root Instance Established with ICANN and China’s ZDNS Cooperation

Introduction of L-Root Instance in China Helps Mitigate Network Outages and Reduce DNS-Related Delays

ICANN logo[news release] A new L-Root instance has been installed in China, increasing the Domain Name System’s (DNS) overall fault tolerance and its resilience against certain types of cyber threats, such as Distributed Denial of Service (DDoS) attacks.

The launch of the L-root server node is a joint operation between ICANN and China’s Internet Domain Name System Beijing Engineering Research Center (ZDNS). As the first Internet domain name system engineering research center in China that focuses on DNS operational and supporting technologies, ZDNS supplied the equipment necessary for the installation of the new L-Root node, in close collaboration with the Beijing Internet Institute.

“The introduction of the L-Root mirror will significantly increase the inter-networking efficiency of Chinese Internet. The improved infrastructure not only benefits the at-large Internet users with regards to their user experiences, but also provides a firm basis to various Internet applications,” said Wei Mao, Director General of ZDNS.

The cooperation between the two organizations is an effort to enhance security, stability and resiliency to Chinese Internet users and reduce the response time experienced when making some DNS queries.

“The stability and resiliency of the global Internet continue to be strengthened with ZDNS installation of the L-Root instances,” said ICANN President and CEO Fadi Chehadé.

“We’re pleased to complete this second L-Root instance installation in China this year, after a similar cooperation with 21Vianet. ICANN will continue to work with other Chinese partners to bring in more L-Root instances into the country,” said Kuek Yu-Chuang, Vice President and Managing Director for ICANN Asia Pacific Hub.

There are 13 “root” DNS servers, identified by alphabetic letters A through M – the “L” root server operated by ICANN being one. Computers typically communicate with each other using numeric addresses, while humans find it easier to use and remember names (for instance, users typically remember the domain name “ICANN.ORG” more easily than the Internet Protocol address, 2620:0:2d0:200::7). The DNS translates names into addresses and the root servers provide the pointers to the servers for top-level domains (the last part of domain names, for example, “ORG” in “ICANN.ORG”). Spreading this root information out geographically by duplicating the root servers leads to a resilient, dispersed system that reduces the risk of being taken offline by a problem or attack and reduces the time it takes to look up names on the Internet.
