Deployment of the IPv6 standard has seen a rapid increase in the past decade with Google currently measuring 25-30% of their traffic being served over native IPv6 connections, 25% of all Internet-connected networks advertising IPv6 connectivity, and major mobile networks such as T-Mobile embracing the standard. Accordingly, there is an urgent need for censorship circumvention tool developers and researchers to measure how IPv6 deployments are impacting online information control systems, and how the emergence of IPv6 could enable novel circumvention techniques to augment existing tools. The overall objective in this project is to develop measurement methodologies to track IPv6-specific information control deployments and develop new circumvention strategies which leverage features of the IPv6 deployment and protocol. The research can have wide reaching near and long term impact in terms of facilitating free and open communication over the Internet. The project makes the following technical contributions. First, the project measures how information controls deployments are modified to handle IPv6 traffic. The project seeks to understand how IPv6 is handled by information controls deployments. To this end, the investigators explore two directions: updating existing IPv4-specific measurement techniques and platforms to make them IPv6-capable and developing new measurement techniques utilizing the IPv6 protocol to improve information controls measurement capabilities. Second, the project designs schemes that leverage the IPv6 protocol to bypass online censors in the short- and long-term. The goal is to understand how the IPv6 protocol can aid censorship circumvention. To this end, the researchers explore three directions: (1) making short-term gains against censors by leveraging IPv6 transition technologies, (2) advancing the state of Refraction Networking technologies by using IPv6, and (3) developing clean slate IPv6 based circumvention tools.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

在过去的十年中，IPv6标准的部署迅速增长，目前Google的量度为本机IPv6连接的25-30％的流量，所有与Internet连接的网络的25％广告IPv6连接性以及主要的移动网络（例如T-Mobile）采用该标准。因此，迫切需要审查制度的工具开发人员和研究人员来衡量IPv6部署如何影响在线信息控制系统，以及IPv6的出现如何使新颖的弯曲技术能够增强现有工具。该项目的总体目标是开发测量方法，以跟踪特定于IPv6的信息控制部署并制定新的规避策略，以利用IPv6部署和协议的特征。这项研究在促进互联网上的自由和开放式沟通方面可能会产生很大的近距离影响。该项目做出以下技术贡献。首先，该项目衡量如何修改信息控制部署以处理IPv6流量。该项目旨在了解信息控制部署如何处理IPv6。为此，调查人员探索了两个方向：更新现有的IPv4特定测量技术和平台，以使它们具有IPv6协议，并开发了IPV6协议的新测量技术，以改善信息控制能力。其次，该项目设计了利用IPv6协议的计划，以短期和长期绕过在线审查员。目标是了解IPv6方案如何帮助审查制度规避。为此，研究人员探索了三个方向：（1）通过利用IPv6过渡技术来对审查员进行短期收益，（2）通过使用IPv6来推进折磨网络技术的状态，（3）（3）开发基于IPV6的清洁SLATE IPV6基于IPV6的限制奖励，这些奖项反映了NSF的构建范围。 标准。
