SAC090 - SSAC Advisory on the Stability of the Domain Namespace


This advisory is concerned only with the risks to security and stability that arise from ambiguity in the use of the domain namespace. Because no one owns (or can own) the domain namespace, and programmers and network managers cannot be prevented from creating their own names and naming scopes, these risks arise regardless of how policy debates about authority or oversight are resolved. Therefore, the observations and recommendations in this advisory are directed at mitigating clearly identified risks and developing policies that provide practical guidance to software and system developers, rather than debating whether or not private network operators should use the domain namespace, or who (if anyone) should have the authority to declare and enforce exclusive uses for specific individual domain name labels or categories of labels.
