large ranges of Internet addresses were reserved and set aside in advance for use by private networks:
| Network Designation |
First Address |
Last Address |
Number of Addresses |
| 192.168.0.0/16 |
192.168.0.0 |
192.168.255.255 |
65,536 |
| 172.16.0.0/12 |
172.16.0.0 |
172.31.255.255 |
1,048,576 |
| 10.0.0.0/8 |
