Introduction

The RIPE NCC operates k.root-servers.net, one of the 13 Internet root name servers. The K-root service is provided by a set of distributed mirror instances using IPv4 and IPv6 anycast. Each mirror instance announces the 193.0.14.0/24 prefix in AS25152. Additionally, some instances announce the 2001:7fd::/32 prefix in AS25152. A K-root mirror instance consists of a cluster of server machines running the NSD name server software.
