The CBQ Class object which divids the destination IP address
into ranges according to its divisor for its immediate children
of AutoClasses. Each dynamically created child will be assigned to
AutoClass of that range. For example,
an IP range: 198.200.0.0-198.200.0.255, divisor: 4.
The ranges will be divided as following:
198.200.0.0 - 198.200.0.63
198.200.0.64 - 198.200.0.127
198.200.0.128 - 198.200.0.191
198.200.0.192 - 198.200.0.255
An IP source address of 198.200.0.18 will fall into
the range of 198.200.0.0 - 198.200.0.63.
Divisor must be a positive number. No divisor will be applied
at its zero value.
