Question

What three blocks of addresses are defined by RFC 1918 for private network use?

1) 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16
2) 10.0.0.0/8, 172.16.0.0/16, 192.168.0.0/24
3) 10.0.0.0/16, 172.16.0.0/12, 192.168.0.0/8

Answer 1

The three blocks of addresses defined by RFC 1918 for private network use are: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16.

Step-by-step explanation:

The three blocks of addresses defined by RFC 1918 for private network use are:

1. 10.0.0.0/8
2. 172.16.0.0/12
3. 192.168.0.0/16

RFC 1918 specifies these address ranges for private networks. These addresses are not routable on the internet and can be used for internal IP addressing within organizations. For example, if you want to set up a private network within your home or company, you can use any IP address within these three blocks to assign to your devices, such as computers, printers, or IoT devices.

10.0.0.0/8: This block ranges from 10.0.0.0 to 10.255.255.255, providing a large address space for private networks.

172.16.0.0/12: This block spans from 172.16.0.0 to 172.31.255.255, allowing for a significant number of private IP addresses within this range.

192.168.0.0/16: This block covers the range from 192.168.0.0 to 192.168.255.255, offering another substantial address space for private network use.
