Comparison of IPv4 vs IPv6 – The Internet Protocol
This is the Comparison of IPv4 vs IPv6 The Internet Protocols Computers and devices can communicate over the Internet thanks to Internet Protocol (IP).IP comes in two flavors: IPv4 and IPv6.. Both are used to refer to devices connected to a network but differ in several aspects.
In this article, you can learn to differentiate between IPv4 and IPv6 and what is the future of the two versions of the Internet Protocol.
What Is an Internet Protocol?
there are the Comparison of IPv4 vs IPv6 The Internet Protocols IP is a set of rules responsible for routing data across networks and delivering it to the correct destination. When sending data over a network, a computer divides the information into bits called data packets, making the data transfer process faster and more efficient. Each of the data packets contains the IP address of the source and the destination. An Internet Protocol address is a Unique number assigned to every device connected to the Internet or network. Just like you need a postal address to send a letter, a device also needs the correct IP address to Information over the network.
A simple example of IP addresses:
212.1.212.62
IP addresses are distributed by the Internet Assigned Numbers Authority (IANA) in the United States, which manages the IP address pool. Always remember domain is easier to remember than numeric IP addresses,
What is IPv4?
Internet Protocol version 4 (IPv4) is the List and best-known version of the Internet Protocol. It is subject to a best-efforts delivery method which does not guarantee delivery of data or quality of service, This means that users may experience delays and other issues depending on the current Internet traffic load. IPv4 is also a connectionless protocol that transmits packets without ensuring that the target device is ready. The advantage of this protocol is that it can send packets through an alternate path in the event of network congestion or router errors.
This version of IP employs 32-bit addresses, which are the most commonly used format when discussing IP addresses.. An IPv4 address consists of four decimal numbers separated by three dots and The range of values in IPv4 is from 0 to 255.. for example:
192.0.2.146
The 32-bit address provides about 4.
What Is IPv6
Internet Protocol version 6 (IPv6) is a newer version of IP, also known as Internet Protocol Next Generation (IPng).
Like Internet Protocol version 4 (IPv4), Internet Protocol version 6 (IPv6) also offers distinct addresses for every device connected to the internet. However, unlike IPv4, IPv6 uses a 128-bit address format rather than a 32-bit address format.
A 128-bit address space provides about 340 billion addresses, 1028 times more than IPv4 addresses. The IPv6 address contains numbers and letters. It is written as eight sets of four-digit hexadecimal numbers separated by colons.
A simple example of an IPv6 address:
2001:db8:3333:
:CCCC:DDDD:EEEE: FFFF
IPv6 has advantages over IPv4, one of which is the availability of a larger number of IP addresses. Additionally, the IPv6 header is simpler than that of IPv4. The IP header is important information located at the beginning of an IP packet…
The header for IPv6 comes with a new format designed to minimize header overhead for more efficient packet processing.
Another difference between IPv4 and IPv6 is superior to IPv4, primarily because it includes IP Security (IPSec), a protocol that secures network communications at the IP layer.
It also facilitates the implementation and deployment of services such as Voice over Internet Protocol (VoIP) and Quality of Service (QoS).
Why we need two IPv4 versions?
While the maximum number of IPv4 addresses may appear to be substantial, it is still insufficient to meet the demands of all the connected devices worldwide, particularly with the increase in the number of IPv4 devices.. the Internet of Things (IoT).
This is why IPv6 came to meet the need for more Internet addresses. However, the use of IPv4 is still necessary as the world begins to adopt this protocol.
While many major content providers such as Facebook and Netflix are now accessible via IPv6, there are only 19.
1% of the top 10 million websites on Alexa are accessible through the protocol, showing that full adoption of IPv6 is still a long way off.
Why do we need two IP versions?
Comparison of IPv4 vs IPv6 The Internet Protocol IPv4 addresses seem high, but it is not enough to manage all connected devices in the world, because of the rise of Internet device objects. This is why IPv6 came to meet the need for more internet addresses. However, the use of IPv4 is still necessary as the world begins to adopt this protocol.
While many large content providers such as Facebook and Netflix are now accessible via IPv6, only 19.1% of Alexa’s 10 million sites are accessible via the protocol, showing that full adoption of IPv6 is IPv4 vs IPv6-Security still far from over. IPv6 has numerous advantages over its predecessor, IPv4, and one of the most significant benefits is the inclusion of IP Security (IPSec) protocol. This security protocol is designed to safeguard network communications at the IP layer, enhancing the overall security of IPv6 networks.
IPSec has three components that protect different aspects of network communications:
Authentication Header (AH) –
Helps the network verify the source of the packet and whether the transmission has been modeled. They also prevent hackers from creating fraudulent packages to deliver malware to devices or apps.
Encapsulating Security Payload (ESP) –
Adds encryption and another layer of authentication to secure data transmission.
ISAKMP (Internet Security Association and Key Management Protocol) –
Defines the security capability that two devices will use to exchange data. Although IPSec can also be used with IPv4, its use depends on the network provider and the end user. The framework also does not apply to NAT-based communication. Another security benefit of IPv6 is that it can perform end-to-end encryption and integrity checking. which makes man-in-the-middle (MitM) attacks more difficult. IPv6 also uses the Secure Nelabbor Discovery (SEND) protocol, which provides a more secure name resolution. This makes it harder for an attacker to redirect traffic between two legitimate hosts and observe or manipulate the conversation. IPv6 can lead to better security solutions than IPv4, but those security features also depend on the proper design and implementation of IPv6. It is also important that firewalls, access control systems, and anti-virus software are enabled. IPv4 vs IPv6-Speed
Securely, a security service provider, conducted a series of tests on sites that support both IPv4 and IPv6, and discovered that both offer the same speed in a direct connection.. However, there is more evidence that IPv6 is faster than IPv4. One of them is a study by Akamai showing that IPv6 outperforms IPv4 on the four largest US mobile networks. The other is an observation by Facebook Engineering that accessing Facebook over IPv6 is 10-15% faster than using IPv4
The difference between IPv4 and IPv6 is that it is slightly faster than IPv4 because connections go Styles directly to the network.
The Future of IPv4
Comparison of IPv4 vs IPv6 The Internet Protocols Only a handful of IPv4 addresses are available today. The RIPE NCC, Regional Internet Registries (RIRS), announced that it has run out of IPv4 addresses. However, until we completely disable IPv4. IPv4 will continue to be used on the web for the foreseeable future. Here are a few reasons: Replacing IPv4 equipment is expensive. Upgrading software and hardware designed for IPv4 is expensive and time-consuming. Lack of compatibility. Many legacy devices and systems are still not compatible with IPv6. This can lead to some issues, including DNS errors.
