A year ago, the US held 1324.93 million addresses out of a total of  
2238.04 million = 59.2% (apparently I rounded off incorrectly with my  
60% figure).

Yesterday's total is 2407.11 so for the US to maintain its 59.2% it  
would have to hold 1425 million addresses, which is an increase of  
exactly 100 million addresses. But the US didn't get 100 million  
addresses last year, but "only" 41.66 million for a total of 1366.53  
(56.8%).

So the US keeps growing, and still uses up a quarter of the new  
addresses given out in 2006, but the rest of the world grows faster  
so the US lead is diminishing.
