What is an IP address? Describe its structure.
What will be an ideal response?
In IP-based networks, each computer (or each network interface of a computer) has a unique, 32-bit IP address.
For the sake of readability, these 32 bits are not shown as a sequence of 32 zeros and ones, but are divided into 4 bytes. These four bytes, called octets, are separated by dots (32-bit/4-byte dot notation, or dotted quad notation) and are recorded either as decimal or binary numbers.
For example, 32 bits "in sequence" from the machine's point of view looks like the following:
11000000 10000001 00110010 00000001
Readable IP representation in decimal format looks like the following:
192.129.50.1
An IP address consists of the network prefix (the front part of the IP address) and a host number (the end part of the IP address).
The network prefix helps to determine the network class in which the host is located. By means of the IP address, data is delivered to the required host in the destination network.
