Paul Vixie, founder and chairman of ISC, Paul Vixie, visits the replica of the F root server installed CATNIX

The founder and chairman of ISC, Paul Vixie, visited CATNIX last Friday 22nd to see the F root server replica, one of the two located in Spain. Vixie took advantage of its stay in Barcelona to give a conference to see CESCA’s technological facilities.

CATNIX has a F-root name server replica managed by the Internet Systems Consortium (ISC) since 2005. This server accepts both IPv4 and IPv6 queries and it allows not only to improve the quality of service in the response time for the DNS queries but also to increase the security, because it guarantees the service operation in case of DDoS attacks.

The DNS is an Internet cornerstone based on a hierarchical structure, where millions of servers around the world are part of the information needed to make things work. The root system consists of 13 servers which are named with the first 13 letters of the alphabet (A to M). Ten of these servers, all equal, 10 are in the United States, while only two are located in Europe and Japan. The small number of the root servers and the high concentration in the U.S. means security and stability weaknesses, especially in case of DDoS attacks. Therefore, it is vital to have mirrors throughout the world in order to improve the safety and availability of this service critical for network performance, as when the DNS does not work or its access degrades, typical applications (web, email, etc..) are disabled or penalized. There are currently 51 F replicas servers in the world, ten of them in Europe.
