Like its predecessor, this new server is a Calypso model and is based on the Dell PowerEdge R260 platform, equipped with a Quad CPU at 3.4 GHz, 16 GB of RAM and two 480 GB SSD drives.
In addition to the L-root server, CATNIX hosts others essential replicas, such as the F and J root servers, as well as replicas of the .com and .net domains. The presence of these systems within the local infrastructure significantly improves DNS query response times, as latency is reduced by having copies physically close to users.
This proximity also enhances the security and resilience of the system. In the event of a Distributed Denial of Service (DDoS) attack, the distribution of replicas around the world minimizes global impact and prevents localized saturation from affecting overall DNS operation.
Currently, the DNS root system is made up of 13 main servers, named with the letters A through M. Although they all provide the same service, their geographical distribution is uneven: 10 are located in the United States, two in Europe, and one in Japan. Without the presence of hundreds of internationally distributed replicas, such as those hosted at CATNIX, this concentration could become a significant structural weakness, both in terms of security and stability when facing potential attacks.
