Final answer:
Three examples of private IPv4 addresses are 192.168.1.1, 10.0.0.1, and 172.16.0.1. These reside within the larger blocks of 192.168.0.0/16, 10.0.0.0/8, 172.16.0.0/12, which are reserved for private use and not routable on the global internet.
Step-by-step explanation:
Private IPv4 Addresses
Private IP addresses are defined by the Internet Assigned Numbers Authority (IANA) and are used within a network to communicate between devices without being directly exposed to the internet. These addresses are not routable on the global internet. Here are three examples of private IPv4 addresses:
- 192.168.1.1 - Commonly used for routers and other devices within a home network.
- 10.0.0.1 - Often used in large corporate networks.
- 172.16.0.1 - Used in mid-size networks; part of a range from 172.16.0.0 to 172.31.255.255.
Each of these IP address ranges are part of larger blocks specifically reserved for private use:
- 192.168.0.0 to 192.168.255.255 (16-bit block)
- 10.0.0.0 to 10.255.255.255 (8-bit block)
- 172.16.0.0 to 172.31.255.255 (12-bit block)
Network devices using these private addresses can still access the internet through a process called Network Address Translation (NAT).
