Understandably so. The Internet has grown from a hobby to a critical infrastructure underlying commerce and industry. It is reasonable for many countries to be wary of having critical administration of Internet operation to be under even the potential influence of the US government (or any other, for that matter).
Frankly, I have some concerns with a for-profit organization like Verisign administering the .com and .net domains. But generally, I think ICANN has done a pretty good job, and am unaware of the particular criticisms that developing countries have raised. Content control and taxation issues should not drive this change.
On the other hand, the ITU is hardly a body worthy of paranoia. Sure, it is a “specialized agency” of the UN, but it actually pre-dates the UN, and would not be subject to the Human Rights declarations referenced in the OP. It isn’t part of the General Assembly, the Security Council, or the International Court of Justice. The ITU has its own governing body, budgets, standards, and guidelines.
Suggesting that the UN wants the Internet is simply misleading. It would be more accurate to say that some parties have expressed concern with the potential influence the US could (or does) have over ICANN, and that the administration might better be handled by the ITU.
On the face of it, it seems reasonable to consider. Unaware of the issues that would necessitate such a change, I would not support it. But I’ll keep an open mind.
Sort of. The real power of ICANN is controlling the IP addressing scheme. IP address administration is a critical operation of the Internet Protocol - the core technology that drives the Internet (under control of IETF, btw).
Top level domain administration happens to be a basic technological underpinning of the World Wide Web and some other popular applications (often confused with the Internet, but they are simply the most popular applications riding the Internet). It would not be particularly difficult for a group of users to completely bypass the “official” DNS system. You can, for example, access the SDMB without ever using the DNS system (less user friendly, granted, but possible nonetheless).
