Class C
Class C addresses are assigned to groups that do meet the qualifications to obtain Class A or B addresses.
The first three binary digits of a Class C address must be 110, which means that Class C addresses can range from 192 through 223.
In Class C addresses, the last five digits are configurable.
The graphic on the next slide shows that when the last five digits are set to all zeros, the decimal equivalent is 192.
When those same five digits are set to binary ones, the decimal equivalent is 223.
