DNS (Domain Name System)
The RIPE NCC provides a variety of DNS related services, including operating k.root-servers.net, one of the 13 Internet root name servers. The K-root service is provided by a set of distributed nodes using IPv4 and IPv6 anycast.
Each node announces prefixes from 193.0.14.0/23 in AS25152. Additionally, some nodes announce prefixes from 2001:7fd::/32 in AS25152. A K-root node consists of one or more servers running BIND, Knot or NSD.
Our Authoritative DNS (AuthDNS) cluster announces 193.0.9.0/24 and 2001:67c:e0::/48from AS 197000. The service hosts reverse DNS zones, ripe.net, and provides secondary service for various ccTLDs.
