For several years, AFNIC has been using anycast technology, which enables the distribution of a DNS name server over multiple geographically dispersed servers.

As the geographical spread increases, this technology improves the quality of the DNS service in terms of response time – always shorter – and strength. Also, by multiplying the number of hosts, it provides a better resistance to denial of service attacks.

Today, AFNIC has chosen to deploy this technology on its own, and is currently setting up a new anycast cloud, complementing the ones already handled by its providers. This new anycast cloud – which supports both IPv4 and IPV6 – will be deployed first in France and on the Reunion Island, the main part being hosted on Renater facilities.

GIP RENATER provides, since mid-may, a replica of root server « I » on the SFINX PoP hosted by InterXion.
The setting up of this root server « I » replica illustrates RENATER’s policy to optimize the access to the Internet Naming service. With this initiative, RENATER offers the French and European Internet Community response times as short as can be. Indeed these server are not only advantageous for French and European Education and Research Community, but also to every operator and provider present on SFINX.

This service is redundant thanks to the hosting of 3 distinct replicas (« F », « M » and now « I », that is 3 servers on the 13 Internet root servers ) split on the 2 points of presence of  SFINX, and it is added to the numerous other services provided by SFINX.
We remind you that SFINX (Service for French INternet eXchange) assures today the network between more than 80 operators (national, but also international), and represents one of the main exchange points in France and Europe.
