K-root Nodes
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 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.
Host a K-root node
Anyone may apply to host a K-root node. Get details on the expansion plan and application process.

Peering with K-root
