(October 2015) Neutering, from the Latin neuter (of neither sex), is the removal of an animal's reproductive organ, either all of it or a considerably large part. Neutering is often used incorrectly to refer only to male animals, but the term actually applies to both sexes.
The CIDR address we specified indicates that the first 23 bits are used for the network block we are referencing. This is equivalent to a netmask of 255.255.254.0, or: 1111 1111 - 1111 1111 - 1111 1110 - 0000 0000
Since the IP is made up from 32 binary bits, the answer is 32 bits less 31 bits equals one bit, so the answer is: Now what if we wanted XX.XX.XX.0 thru XX.XX.XX.9 (A range of 10 IP numbers). Now it gets a bit more complicated: Because a CIDR can only express a power of 2, it can express 1, 2, 4, 8, 16, 32, 64 etc.
