The broad strokes of US policy makers are about to claim “ownership” of such a wide swath of the Internet that will effectively give them total control. As Michael Geist explains:
“The U.S. Congress is currently embroiled in a heated debated over the Stop Online Piracy Act (SOPA), proposed legislation that supporters argue is needed combat online infringement, but critics fear would create the "great firewall of the United States." SOPA’s potential impact on the Internet and development of online services is enormous as it cuts across the lifeblood of the Internet and e-commerce in the effort to target websites that are characterized as being "dedicated to the theft of U.S. property." This represents a new standard that many experts believe could capture hundreds of legitimate websites and services”
The definitions are so broad that they capture many sites that are certainly not US in any way.
“First, it defines a "domestic domain name" as a domain name "that is registered or assigned by a domain name registrar, domain name registry, or other domain name registration authority, that is located within a judicial district of the United States." Since every dot-com, dot-net, and dot-org domain is managed by a domain name registry in the U.S., the law effectively asserts jurisdiction over tens of millions of domain names regardless of where the registrant actually resides.
Second, it defines "domestic Internet protocol addresses" - the numeric strings that constitute the actual address of a website or Internet connection - as "an Internet Protocol address for which the corresponding Internet Protocol allocation entity is located within a judicial district of the United States."
Yet IP addresses are allocated by regional organizations, not national ones. The allocation entity located in the U.S. is called ARIN, the American Registry for Internet Numbers. Its territory includes the U.S., Canada, and 20 Caribbean nations. This bill treats all IP addresses in this region as domestic for U.S. law purposes.
To put this is context, every Canadian Internet provider relies on ARIN for its block of IP addresses. In fact, ARIN even allocates the block of IP addresses used by federal and provincial governments. The U.S. bill would treat them all as domestic for U.S. law purposes.”
