K-root Nodes

The RIPE NCC operates, 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 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.

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

K-root originates all our prefixes from AS25152. We operate a generally open peering policy, subject to certain operational policies.

ICANN's Root Server System Advisory Committee (RSSAC) has published a document, RSSAC002, that requests root name server operators to collect and publish certain key metrics about the root name server system. K-root's statistics are available at the following address:

These graphs show the query rate at K-root. The first graph shows the combined rate across all K-root nodes. The next four show combined query rates for the four different categories of K-root nodes. Clicking on the graphs will show more details.
