The subnet address is a dotted IP subnet address and a mask written in the following
format:
dotted_ip

num_bits
dotted_ip
can be
an IP address (a.b.c.d)
or
an IP subnet
a for a class A network
a.b for a class B network
a.b.c for a class C network
The size of the subnet is specified by the number of leading bits of the netmask,
num_bits
