As previously stated, private IP addresses cannot transmit data over the Internet and are only intended to function within the local network. For example, your router assigns a private IP address to each device on your home local network. So you can find your private IP addresses using the co...
You can set any number of these bits to 1 to get a valid IP address in this subnet, with the exception of all 0s or all 1s. Putting it all together, you can see how a host with an IP address of 10.23.2.1 and a subnet mask of 255.255.255.0 is on the same subnet as any other...
