As I tried fervently to explain to you when you demanded IP addresses
while refusing to complete an ISP template, there is information in
the ISP template and the ISP guidelines which is very important to
a start up ISP.  Part of that information is the paragraph below which
deals with the possibility of filtering prefix lengths.  

You are incorrect when you state the paragraph below is only in the
IP template.  The InterNIC has done everything we can to inform the
public of possible future consequences when receiving addresses directly
from the InterNIC.

Please read or reread the ISP guidelines (since you officially agreed
to abide by those policies in an email message to the InterNIC, I assumed you
had already read them).  They can be found at ftp://rs.internic.net/
