Is a /48 still the smallest thing you can route independently?

Wow and I thought nibble boundaries would make the math easier than HD ratios.

Here's the breakdown for those who are mathematically challenged:

n sites			prefix
0			Nothing.
1			/48
2-12			/44
13-191			/40
192-3071		/36
3072-49,151		/32
49,152-786,431		/28

If you're managing more than 786,431 sites, then you should be able to afford
to hire someone who can properly handle the math.
