However, ICANN's and the DoC's reach are reined in somewhat by the knowledge that technically there is still nothing to prevent the world turning its back on them and redirecting to an alternative system. This is why country-code delegations for example have rarely been forcibly changed by ICANN even where existing delegates refuse to kowtow. If they seriously overstep the consensus of their power, they run the risk of outright rebellion. An issue like COICA could for example push the issue too far and have the non-US root controllers abandon ICANN and set up an alternative system. The IP address number assignment system is in fact more of a technical barrier should ICANN try to impose its will. This issue is only now getting the attention it needs due to the IPv4-6 issue. In the end, the Internet as currently constituted is a single consensus reality that holds sway because so far the consensus is preferable to the chaos that might ensue. If the consensus becomes more of a problem than the chaos, ICANN could fail and fall. I heartily recommend Milton's book Ruling the Root, by the way, for anyone getting involved in this area. It gives you the basic background politically and technically to understand the situation. It's a little old now but it covers how we got to the current settlement which has more or less remained for the last nine years. -- Professor Andrew A Adams [log in to unmask] Professor at Graduate School of Business Administration, and Deputy Director of the Centre for Business Information Ethics Meiji University, Tokyo, Japan http://www.a-cubed.info/
