Internet Society Joins Opposition to Stop Online Piracy Act (SOPA)

Policies mandating DNS filtering undermine the open architecture of the Internet and raise human rights and freedom of expression concerns

[Washington, D.C. and Geneva, Switzerland – 12 December 2011] – The Internet Society Board of Trustees has expressed concern with a number of U.S. legislative proposals that would mandate DNS blocking and filtering by ISPs to protect the interests of copyright holders. While the Internet Society agrees that combating illicit online activity is an important public policy objective, these critical issues must be addressed in ways that do not undermine the viability of the Internet as a platform for innovation across all industries by compromising its global architecture. The Internet Society Board of Trustees does not believe that the Protect-IP Act (PIPA) and Stop Online Piracy Act (SOPA) are consistent with these basic principles.

Specifically, the Internet Society is concerned with provisions in both bills regarding Domain Name System (DNS) filtering. DNS filtering is often proposed as a way to block illegal content consumption by end users. Yet policies to mandate DNS filtering will be ineffective for that purpose and will interfere with cross-border data flows and services undermining innovation and social development across the globe.

Filtering DNS or blocking domain names does not remove the illegal content – it simply makes the content harder to find. Those who are determined to download filtered content can easily use a number of widely available, legitimately-purposed tools to circumvent DNS filtering regimes. As a result, DNS filtering encourages the creation of alternative, non-standard DNS systems.

From a security perspective, DNS filtering is incompatible with an important security technology called DNSSEC. In fact, DNSSEC would be weakened by these proposals. This means that the DNS filtering proposals in SOPA and PIPA could ultimately reduce global Internet security, introduce new vulnerabilities, and put individual users at risk.

Most worrisome, DNS filtering and blocking raises human rights and freedom of expression concerns, and often curtails international principles of rule of law and due process. Some countries have used DNS filtering and blocking as a way to restrict access to the global Internet and to curb free expression.

The United States has been a strong proponent of online Internet freedoms and therefore has an important responsibility to balance local responsibilities and global impact, especially with respect to Internet policy. Given this commitment to global Internet freedom, it would be harmful to the global Internet if the United States were to implement such an approach.

“The Internet Society Board of Trustees is deeply concerned about the ramifications of the PIPA and SOPA bills on the overall stability and interoperability of the Internet,” said Raul Echeberria, Chairman of the Internet Society Board of Trustees. “The Board recognizes that there can be misuses of the Internet; however, these are greatly outweighed by the positive uses and benefits of the Internet. We believe the negative impact of using solutions such as DNS blocking and filtering to address these misuses, far outweighs any short-term legal or business benefits.”

“The Internet Society believes that sustained, global collaboration amongst all parties is needed to find ways that protect the global architecture of the Internet while combating illicit online activities,” said Internet Society President and CEO Lynn St. Amour. “Mandating DNS blocking and filtering is simply not a viable option for the future of the Internet. We must all work together to support the principles of innovation and freedom of expression upon which the Internet was founded.”
