If you know that you're going to need more than a /32, be sure to ask  
ARIN for more than the default. But these things are almost impossible  
to get right the first time, so don't sweat it if you have to come  
back for more later. There are more than 8 prefixes per AS for IPv4.  
One prefix per AS for IPv6 is a laudable goal, but it's not a huge  
deal if it's more like 2.
