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.
