ICANN’s Security and Stability Advisory Committee (SSAC) has published a paper on DNS Blocking.

SSAC 50: DNS Blocking: Benefits Versus Harms is available for download in PDF here

The paper isn’t very long and has a short list of points that people should be aware of when considering implementing DNS blocking:

1. The organization imposes a policy on a network and its users over which it exercises
administrative control (i.e., it is the administrator of a policy domain).
2. The organization determines that the policy is beneficial to its objectives and/or the
interests of its users.
3. The organization implements the policy using a technique that is least disruptive to its
network operations and users, unless laws or regulations specify certain techniques.
4. The organization makes a concerted effort to do no harm to networks or users outside
its policy domain as a consequence of implementing the policy.
