In order to secure the DNS system, DE-CIX has deployed AS112 project servers in Marseille.
The aim of the AS112 project is to create a web of DNS servers that catch reverse DNS queries for private IPv4 space. This will reduce the load on so-called DNS root servers and makes the DNS system more secure and robust against DNS DDoS attacks.
DE-CIX announces AS112 on its route servers and makes the AS112 project servers so available for all customers peering with the route servers. Customers do not need to change any configuration.
More information and all available locations for the AS112 service can be found here.
