penciling_in writes "ISC has made the announcement that they have developed a technology that will allow 'cooperating good guys' to provide and consume reputation information about domain names. The release of the technology, called Response Policy Zones (DNS RPZ), was announced at DEFCON. Paul Vixie explains: 'Every day lots of new names are added to the global DNS, and most of them belong to scammers, spammers, e-criminals, and speculators. The DNS industry has a lot of highly capable and competitive registrars and registries who have made it possible to reserve or create a new name in just seconds, and to create millions of them per day. ... If your recursive DNS server has a policy rule which forbids certain domain names from being resolvable, then they will not resolve. And, it's possible to either create and maintain these rules locally, or, import them from a reputation provider. ISC is not in the business of identifying good domains or bad domains. We will not be publishing any reputation data. But, we do publish technical information about protocols and formats, and we do publish source code. So our role in DNS RPZ will be to define 'the spec' whereby cooperating producers and consumers can exchange reputation data, and to publish a version of BIND that can subscribe to such reputation data feeds. This means we will create a market for DNS reputation but we will not participate directly in that market.'"
