And thus, IP addresses are divided into several classes based on the number of digits
in the network number, as illustrated in the figure.

There are some restrictions on device numbers in the IP address, where they cannot
all be zeros or ones, such as binary numbers (255 in decimal). When the device
number is zero, the IP address is considered to represent the network address itself,
such as 10.0.0.0. When the entire device number is all ones, the IP address is
considered to represent the broadcast address, which can send a message to all other
devices at once, such as 10.255.255.255.
Thus, valid IP addresses for devices in the example range from 10.0.0.1 to
10.255.255.254.

10.3Default Gateway:

The default gateway is the intermediary between the local network and the Internet,
usually residing in the network's router. It allows you to connect to the Internet
through an Internet Service Provider (ISP) and operates by "routing" internet traffic
to its correct destination.
