   The problem is that the whole DSL market in Japan is still growing with 
15% per month and it might remain as 10% per month even around the end of 
this year.  Considering that the ultimate market size at the end of the 
year will be around 5 to 6 million users, the  administrative work and 
technical work required for use of IP address is too heavy to be finished 
within the 20% room that is currently enforced so that we will run out of 
IP addresses by the time they are allocated.
   Thus, we might need changes in the regulation so that we can apply for 
new address space with around 60% usage and they are allocated when there 
is still 20% room (80% usage) which is within a month after the 
application.  Currently, we apply when we have exhausted 80% and they are 
allocated when usage is 100% and we start to see customer complaints.
