Two New Instances of RIPE NCC Operated K-root Server Deployed in Switzerland and Poland
24 November 2004 - The RIPE NCC (Réseaux IP Européens Network Coordination Centre) in partnership with CERN and PSNC (Poznan Supercomputing and Networking Center) has recently deployed two new mirror instance of the K-root Internet root name server. One in Geneva, Switzerland at CIXP (CERN Internet Exchange Point) and one in Poznan, Poland at PSNC.
The K-root server is one of the 13 Internet root name servers that resolve lookups for domain names all over the world and form a critical part of the global Internet infrastructure. The Domain Name System (DNS) is a service used to translate between host names and Internet Protocol (IP) addresses by virtually all Internetworking software, including e-mail and web browsers.
The K-root service is provided by a set of distributed mirror instances using IPv4 anycast. Each mirror instance announces the 18.104.22.168/24 network in AS25152. A K-root mirror instance consists of a cluster of server machines running the NSD name server software.
This new instance of the K-root server is one of a set of distributed mirror instances implemented by the RIPE NCC using an IP anycast technique to provide high availability of the K-root service and improve resilience to Distributed Denial of Service (DDoS) attacks while remaining transparent to the end user.
The RIPE NCC has operated the K-root server since 1997 when the first server was installed at the London Internet Exchange (LINX) in London, UK. Since early 2003, RIPE NCC technicians have deployed mirror instances of the K-root server in Amsterdam, Frankfurt, Athens, Helsinki, Reykjavik, Doha and Milan. There are plans to have up to ten instances of the K-root server deployed by the end of 2004.
