Internet Protocol version 4, commonly referred to as IPv4, is a foundational protocol used for identifying and routing networked devices on the Internet. It's a set of rules that govern how data packets are addressed, transmitted, and delivered across computer networks. IPv4 was the first widely adopted version of the Internet Protocol and remains the most widely used version today.

IPv4 addresses are 32-bit numerical labels assigned to devices (such as computers, servers, routers, and other networked equipment) on an IP network. These addresses are usually expressed in a human-readable dotted-decimal format, where each of the four octets (groups of 8 bits) is separated by a period (dot). For example, an IPv4 address could look like "192.168.0.1".

However, the rapid growth of the internet and the increasing number of connected devices led to the exhaustion of available IPv4 addresses. Due to this limitation, a newer version of the Internet Protocol, called IPv6 (Internet Protocol version 6), was developed to provide a vastly expanded address space and address the limitations of IPv4.

IPv6 uses 128-bit addresses and allows for a significantly larger number of unique addresses, ensuring the growth and sustainability of the internet as more and more devices come online. Despite the transition to IPv6, IPv4 remains in use across most of the internet, with various mechanisms and technologies in place to facilitate communication between IPv4 and IPv6 networks.

In summary, IPv4 is the fourth version of the Internet Protocol and serves as the foundation for identifying and routing data across networks. It uses 32-bit addresses, but due to the depletion of available addresses, IPv6 was introduced with larger 128-bit addresses to accommodate the growing number of devices on the internet.

How is IPv4 converted to 32 bit binary?

IPv4 addresses are represented using four sets of decimal numbers, each ranging from 0 to 255, separated by periods (dots). To convert an IPv4 address to its 32-bit binary representation, you need to convert each of these decimal numbers to an 8-bit binary representation and then combine them.

Here's the process:

1. Convert each decimal number to 8-bit binary:

   • For each decimal number (between 0 and 255), you'll need to represent it as an 8-bit binary number. Start by dividing the decimal number by 2 and keeping track of the remainders.

2. Pad with zeroes if necessary:

   • Sometimes the binary representation might not be a full 8 bits. In such cases, pad the left side with zeroes to make it 8 bits long.

3. Combine the binary representations:

   • After converting all four decimal numbers to 8-bit binary, you'll have four sets of 8 bits each. Combine these four sets of binary numbers to get the complete 32-bit binary representation.

Let's go through an example:

IPv4 address: 192.168.1.10

1. Convert each decimal number to 8-bit binary:

   • 192 => 11000000
   • 168 => 10101000
   • 1 => 00000001
   • 10 => 00001010

2. Pad with zeroes if necessary:

   • 192 is already 8 bits long.
   • 168 is already 8 bits long.
   • 1 needs padding: 00000001
   • 10 is already 8 bits long.

3. Combine the binary representations:

   • 11000000.10101000.00000001.00001010

This is the 32-bit binary representation of the IPv4 address 192.168.1.10. Each set of 8 bits corresponds to one of the four decimal numbers in the IP address.
