NaMeX and ISC are proud to announce the renewal of their agreement and deployment of a new F-root instance in Rome.
ISC, founded in 1994 as Internet Software Consortium, Inc., is the organization behind the ongoing development and distribution of the name server software, BIND. ISC operates f.root-servers.net, one of the 13 Root Name Servers in the world — Internet’s central DNS servers.
The ISC-NaMeX relationship dates back to 2003, when ISC and NaMeX first deployed an F root instance in the NaMeX exchange.
Root Name Servers are fundamental to the functioning of the Internet; each and every web address name on the Internet must be looked up in a Root Name Server to be translated into an IP address; the Root Name Servers are the network elements of what is known as the global Domain Name System (DNS). The actual translation of Internet names to numerical addresses is performed by a “recursive server” or “resolver”. Each ISP connected to NaMeX has its own resolvers. Those resolvers can rely on the local F root instance at NaMeX to find the beginning of the search for a name. By providing this resource locally, NaMeX is helping to speed up access to services on the Internet for all the users of the ISP’s in NaMeX.
Clearly, the limited number of Root Name Servers is a potential hazard for Internet security and operation. There are thirteen Root Name Servers each with multiple instances located in different places. NaMeX is hosting an instance of F root, the root server managed by ISC. All F-Root instances have the same data, the same configuration, and the same IP address (22.214.171.124). The routing infrastructure that surrounds each instance (in this case, the NaMeX exchange) is responsible for making that address known.
With the technical solution BGP Anycast, which F Root pioneered, a distributed attack on the DNS root would have a limited effect on Italian users with local access to the NaMeX instance in Rome.
“Renewing the agreement with ISC has strategic importance for our IXP” comments Maurizio Goretti, CEO of NaMeX. “to continue improving the efficiency and security for all NaMeX ISP’s, and consequently for the entire Italian network, given that these ISP’s also represent a significant portion of Italian Internet access providers.”
