(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
A CIDR address includes the standard 32-bit IP address and also information on how many bits are used for the network prefix. For example, in the CIDR address 206.13.01.48/25, the /25 indicates the first 25 bits are used to identify the unique network leaving the remaining bits to identify the specific host.
