Difference Between IPv4 and IPv6

Introduction

In the worlds of systems management and web access, IP addresses are essential for identifying and interacting with devices. Every device connected to a computer network is given an IP address, often known as a Web Convention address. It functions as a source and impartial differentiating proof for information bundles in an organization that adheres to the Web norm.

Overview

An essential component of the web infrastructure, IP addresses allow devices to communicate and exchange data. They are used for a variety of things, including accessing websites, sending messages, making real-time recordings, and that's just the beginning. For example, "192.168.0.1" for IPv4 addresses or "hexadecimal" for IPv6 addresses are popular spotted decimal formats used to address IP addresses.

What is IP?

Internet Protocol is referred to as IP. The sending and receiving of information via the Internet is governed by several rules and protocols. IP essentially provides devices with a standardized method for exchanging data within an organization.

A fundamental component of the Internet Protocol is an IP address. It is a unique mathematical mark assigned to any device connected to a PC organization. IP often assumes a crucial role in identifying and locating devices online. They serve as the target and source addresses for information bundles, enabling the transfer of data between devices.

Types of IP Address

1. IPv4 Address

The most common IP address format is IPv4 (Internet Protocol version 4). They are addressed in a dabbed decimal configuration and are made up of 32 parts that are separated into four octets. The octets are separated by periods and range in value from 0 to 255. As an illustration, the IPv4 address 192.168.0.1 is usual. Although IPv4 addresses have long been the standard, their availability is now constrained by the internet's rapid development and the growing number of devices connected to it.

2. IPv6 Address

IPv6 (Internet Protocol version 6) addresses are accustomed to getting around IPv4 addresses' limitations. IPv6 addresses are organized in a hexadecimal format and are 128 bits long. They are made up of eight groups of four hexadecimal digits, each separated by a colon. One example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. The primary motivating force behind IPv6 was to provide a vast address space to accommodate the growing number of devices and ensure the continued expansion of the internet.

What is IPv4?

The most widely used IP addressing scheme is IPv4, or Internet Protocol version 4. It is the fourth version of the Internet Protocol. Using an essential protocol, devices can communicate online. IPv4 addresses are composed of 32 pieces that are divided into four octets and are addressed using a specked decimal setup. Periods separate each octet, which ranges from 0 to 255.

Examples:

192.168.0.1 is an example of an IPv4 address. Let's break out this address:

Addressing the first octet is 192.

Addressing the next octet is 168.

The third octet is addressed by 0.

1 speaks to the fourth octet.

Drawbacks of IPv4

Following are the drawbacks of IPv4:

1. Limited Address Space: One of IPv4's main drawbacks is its limited address space. IPv4 can provide around 4.3 billion interesting addresses with just 32 components. When the internet first started, this seemed like a great quantity, but the rapid growth of related technology has led to addressing tiredness. Allocating unique IP addresses to new devices is challenging due to the lack of addresses.
2. (NAT) Network Address Translation: It is used to adjust to the constrained address space. NAT enables several devices inside a secure organization to share a single public IP address. It converts private IP addresses used by neighborhood businesses to public IP addresses when communicating with devices online. Although NAT helps regulate IP addresses, it is complex and can interfere with some applications or protocols that rely on direct communication between devices.
3. Complex Subnetting: In IPv4, subnetting is used to divide a network into smaller subnetworks, allowing for effective address determination. However, IPv4 subnetting can be confusing and requires caution to ensure the best possible use of IP numbers. It can be difficult to supervise and organize subnet veils, network classes, and subnet limitations, especially in large organizations.
4. Security and Weaknesses: IPv4 lacks implicit security features, making it more susceptible to attacks from many organizations. Additionally, the limited address space makes it easier for attackers to conduct IP address analysis and surveillance. To reduce security risks in IPv4 organizations, measures like firewalls and interruption identification frameworks are crucial.
5. Absence of Support for Emerging Innovations: IPv4 was designed with limitations in terms of supporting emerging innovations because it was planned many years ago. IPv4 struggles to provide the necessary addressing and availability as Internet of Things (IoT) devices, autonomous vehicles, and other advancements evolve.

What is IPv6?

The sixth iteration of the Internet Protocol, known as IPv6, is intended to supersede IPv4. It was introduced to get around IPv4's drawbacks, particularly its constrained address space. Compared to IPv4, IPv6 addresses, which are 128 bits long, have an enormously bigger address space. Hexadecimal representations of IPv6 addresses are made up of eight sets of four hexadecimal digits, separated by colons.

Examples:

An example of an IPv6 address is 2001:0db8:85a3:0000:0000:8a2e:0370:7334. Let's break down this address:

2001 represents the first group of four hexadecimal digits.

0db8 represents the second group.

85a3 represents the third group.

0000 represents the fourth group.

0000 represents the fifth group.

8a2e represents the sixth group.

0370 represents the seventh group.

7334 represents the eighth group.

Address Format

IPv6 addresses are organized in a hexadecimal format and are 128 bits long. Eight groups of four hexadecimal numbers, separated by colons, make up the address. Driving zeros can be avoided within groups, and back-to-back zero groupings can be packed using a double colon (::). However, to avoid confusion, the double colon must only be used once in an address.

Examples:

2001:0db8:85a3:0000:0000:8a2e:0370:7334 (full representation)

2001:db8:85a3::8a2e:370:7334 (compressed representation)

Benefits of IPv6

Following are the benefits of IPv6:

1. Tremendous Address Space: The essential benefit of IPv6 is its fundamentally bigger address space. With 128 pieces, IPv6 can oblige around 3.4×10^38 interesting addresses. This huge address space guarantees the accessibility of one-of-a-kind addresses for the developing number of gadgets, including IoT gadgets, cell phones, and other associated innovations.
2. Improved Organization Arrangement: IPv6 works on network setup using autoconfiguration. Gadgets can naturally relegate themselves to a remarkable IPv6 address without the requirement for manual design or DHSP (Dynamic Host Setup Protocol) servers. This works on the organization and the board of gadgets in networks.
3. Further developed Security: IPv6 incorporates worked-in security highlights, like IPsec (Internet Protocol Security), which gives encryption and validation of organization traffic. IPsec helps improve the security of correspondences and safeguards against different organization-based assaults.
4. Enhanced Quality of Service (QoS): IPv6 presents stream naming, which takes into account better prioritization and treatment of explicit sorts of organization traffic. This empowers work on the Enhanced Quality of Service (QoS) components, guaranteeing the effective conveyance of basic information, like continuous video or voice interchanges.
5. Support for New Innovations: IPv6 has been intended to help rising advances and headways, like IoT, where countless gadgets require one-of-a-kind IP addresses and proficient correspondence. With IPv6, there is no requirement for workarounds like Network Address Translation (NAT) utilized in IPv4.
6. Productive Steering: IPv6 improves directing effectiveness using various leveled addressing and steering prefixes. This lessens the size of steering tables and upgrades the versatility and execution of organizations.
