IPv4: The Most Popular Internet Protocol

Are you looking for a reliable and secure internet protocol that is also fast and efficient? IPv4 is the answer! The fourth version of the Internet Protocol, IPv4 is the most widely used version of IP and is the first choice of many networks due to its long-term stability and compatibility. Read on to learn more about the benefits of IPv4, its common uses, and why it is still the most popular Internet Protocol.

What is IPv4 and why is it so popular? 

IPv4 is the fourth version of the Internet Protocol (IP), a communications protocol used for connecting computers and devices on the Internet. It is the most widely-used version of IP and the version of the protocol most Internet services are based on. IPv4 provides faster and more reliable network communications, simplifying data transfer between Internet hosts. As the original version of IP, Internet Protocol version 4 is the first choice of many networks due to its long-term stability and compatibility and therefore is still the most popular Internet Protocol.

The Benefits of IPv4: Speed, Reliability and Security 

IPv4 is a well-established networking protocol and its benefits make it the most popular network protocol for many organizations. One of the most advantageous benefits of IPv4 is the speed. Internet Protocol version 4 supports direct communication between hosts over short distances. This reduces latency and packet round-trip times, making information transfer much quicker.

Along with speed, it is known for its reliability. The protocol is able to adapt and maintain a connection even in times of high traffic or congestion. This ensures that information is sent and received quickly and efficiently without any interruptions.

Finally, it is a secure protocol. When used properly, IPv4 can provide an extra layer of protection to sensitive information. With its built-in packet filtering, anti-spoofing security, and other features, IPv4 helps keep networks and data safe. Overall, its benefits of speed, reliability and security make IPv4 the perfect choice for many organizations.

Common Uses of IP version 4

IPv4 is the most widely used network protocol. We use it for a variety of applications including networking, web browsing, and downloading. Some of the most common uses of IPv4 include connecting devices to the Internet, routing data between source and destination, establishing Virtual Private Networks (VPNs), managing networks, and controlling traffic. 

In addition, Internet Protocol version 4 is also commonly used for voice over Internet Protocol (VoIP). VoIP technology is a type of service that allows users to make phone calls over the internet. VoIP has become an increasingly popular solution among businesses because of its cost-effectiveness and its ability to provide calls with excellent quality and reliability, making it ideal to be used with IP version 4 . 

Overall, Internet Protocol version 4 is a versatile protocol and its use cases are only limited by the imagination of the user. From basic home networking to complex corporate IT infrastructure, IPv4 is a great and reliable choice.

IPv4 vs. IPv6: Comparing Features and Advantages 

IPv4 and IPv6 are the two current versions of the Internet Protocol, and they are often compared due to their similarities and differences. Internet Protocol version 4 is the most widely used version of IP. While IPv6 is the newest version with improved features. One of the major differences between the two is the number of available IP addresses. Internet Protocol version 4 has a limited amount of addresses which is running out, while IPv6 can provide a virtually unlimited amount of public IP addresses. 

When it comes to features and advantages, IPv6 offers many improvements compared to IPv4. IPv6 supports larger packet sizes and faster speeds from end-to-end. And its larger IP address space is better suited for Internet of Things (IoT) deployments. Additionally, IPv6 contains more secure authentication options than Internet Protocol version 4, making it more difficult for malicious actors to attack the network.

FragmentationPerformed by sender and forwarding routersPerformed by sender only
Header ComplexityMore complex, with 14 fieldsSimplified, with 8 fields
BroadcastsUses broadcastsDoes not use broadcasts, uses multicasts instead
NAT (Network Address Translation)Widely usedNot needed due to large address space
Quality of Service (QoS)Not explicitly designed for QoSFlow Label field can be used to identify packet flow for QoS

In conclusion, the main differences between IPv4 and IPv6 are the number of available IP addresses and security features. While both protocols provide core features for communication on the internet, IPv6 offers more advantages for modern networks.


It’s clear why IPv4 is still the most popular Internet Protocol. Because its advantages of speed, reliability and security make it the ideal choice for many networks. Whether you are looking for a simple home networking solution, or a complex corporate IT infrastructure, Internet Protocol version 4 is the perfect choice. With its wide range of uses, its reliable performance and its secure authentication, you can rest assured that IP version 4 will keep your data safe and your network running smoothly. So why not make the switch to IPv4 today?
