Designed by the AFNIC’s R&D department as part of its generic DNS measurements platform, DNSwitness is a multi-purpose software that measures information published in the DNS. Its objective is notably to measure the IPv6 deployment in the network services through the DNS zones delegated under .fr.
As an example, DNSwitness in its current version looks for SPF records (the standard for authenticating the domain name of an e-mail sender) as well as the DNSsec records (security extensions for the DNS protocol based on cryptographic signatures) or the IPv6 protocol. DNSwitness is modular and multi-purpose tool that scans all the sub-zones of .fr, like wikipedia.fr or service-public.fr for example, looking for these data it then stores in a database, on a module basis, and updates regularly.
Available as an open source software (www.dnswitness.net), DNSwitness should interest technicians that plan and unfold new networks or services, salesmen looking for new markets or researchers style-conscious to decode the major and current trends, all needing reliable and regularly updated data. DNSwitness already counts many modules and is easily extensile to new ones, according to the needs and wishes expressed in terms of new features.
The first DNSwitness measurements made by the AFNIC show that:
15% of domain names under .fr have SPF records;
almost no domain names under .fr are signed with DNSsec;
4% of .fr domain names have an IPv6 address published, for the web, e-mail or the DNS. However, only 0.03% of these .fr domain names have an IPv6 address for all these three services at a time.
As the DNS can witness, efforts remain to be made on these technical aspects, though the responsibility is shared between the different parties of the value chain.
