Hosting a DNS node
The RIPE NCC is open to considering requests to host a DNS node in ISPs and other networks.
If your organisation is interested in hosting a DNS node, we kindly ask you to read all of the following documents before you apply:
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 22.214.171.124/23 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 126.96.36.199/24 and 2001:67c:e0::/48 from AS 197000. The service hosts reverse DNS zones, ripe.net, and provides secondary service for various ccTLDs.
The cluster is composed of three core instances located in Amsterdam, London and Stockholm. At each of these sites, a router distributes the DNS queries across multiple servers, running a mix of BIND, Knot DNS and NSD.
The capacity of these core sites is supplemented by Hosted DNS instances. These single-server instances run in ISP networks or are connected to Internet Exchanges. If you would like to host such a server, please send us your application.
