WS100: Carrier Grade NAT Impacts on Users, Markets and Cybercrime [CB]

One tool for conserving IPv4 addresses is called Carrier Grade Network Address Translation, or simply CGN.

This workshop will discuss the implications of the deployment of CGNs on Internet users, applications designers, law enforcement and access providers.

However, the use of Network Address Translation doesn’t come for free. However, recent research shows that Internet application developers and Internet users will bear most of the impact of CGN implementation:

• How will developers of applications, such as online gaming and VoIP, cope with multiple CGN implementations - having to find workarounds for each?
• What will consumers do when they find that applications they count on no longer function correctly and that troubleshooting those problems becomes more difficult?
• Will Law Enforcement be able to manage when they find that traditional techniques for identifying and tracking criminals no longer work in the presence of CGNs?

This means that access to the Internet, that most basic foundation of the Internet’s global success, is substantially different than it was just five years ago. What does this mean for Internet Governance? Clearly, this is an area where new technology has implications for Internet governance and policy making.

The Internet ecosystem distributes decision-making throughout the network of networks and throughout the network of stakeholders. The decision of ISPs to deploy CGN technology is an example of a case where individual decisions at some points of the network have implications on a much wider range of Internet stakeholders and users.
