In this article, you are going to read about the What is IPv4 and IPv6 their Functions, Types, Examples, Advantages, and Disadvantages, Differences between IPv4 vs IPv6 much other information related to this article, so stay on this site for further information.

What is IP Address

An IP address stands for Internet Protocol address. IP addresses are specified numbers that read computer network interfaces.

Although we all use their names to refer to everything on the Internet, such as www. example. in, the computer network translates these names into a numeric address so that they can send data to the correct location.

So when you send an email, or visit a website, or participate in a video conference, your computer sends data packets to the IP address on the other end of the connection, and the packet assigned to your own IP address Receives.

What is IPv4 and IPv6

Here you will get information about what is IPv4 and IPv6, their advantages and disadvantages, and many more details.

IPV4:-

(IPv4) Internet Protocol version 4 is the fourth version of the (IP) internet protocol and it is the first version of the protocol to be widely deployed. Together with IPv6, it is at the core of standards-based internetworking methods of the Internet.

IPv4 Internet Protocol version four is still by far the most widely deployed (IP) Internet protocol. It uses a 32 bit addressing and allows for 4,294,967,296 unique addresses.

What is IPv4 and IPv6

Network Every computer or network device connected to an Internet network must have a specific IP address to communicate with all other systems on the Internet. So because the number of systems connected to the internetwork is getting closer to the number of available IP addresses, IPv4 addresses are predicted to run soon.

As you know, there are more than 6 billion people in the world and many people have more than one system connected to the Internet (eg, home, school, work, etc.), so it is not surprising that roughly 4.3 There are a billion addresses. Not enough.

To solve this problem, a new 128-bit IP system, which has been developed as IPv6 and is in the process of replacing the current IPv4 system. It is during this transitional process from IPv4 to IPv6, each of the systems connected to the Internet can be given both IPv4 and IPv6 addresses.

Advantages of IPv4:-

  • Encryption IPv4 (Internet protocol version four) takes security measures to encrypt data packets in its address packets.
  • Flexibility  the process of network routing has become more efficient in IPv4. Therefore, for organizations that regularly use multicast, their data transmission has been more specific.
  • System Support The IPv4 network routing present inside the IPv4 network protocol can be handled easily by all the computers and systems. 
  • Device Connectivity The primary function of IPv4 is to connected to different types of devices all across the largest network.

Disadvantages of IPv4:-

  • Configurations IPv4 needs configuration either manually or automatically. Configuring IPv4 manually has to be done through Dynamic Host Configuration Protocol (DHCP).
  • Security Internet Protocol Security (IPSec) enables network security to IPv4 by specifying the use of the internet.
  • Access Space Depletion of Public address is another problem faced while using IPv4. This is mainly due to the initial address class allocation practices. 
IPv6:-

Each computer system and the network device connected to the Internetwork is located at an IP address. The current system of distributing this IP address is called IPv4. The system provides 32-bit and numerical addresses to each computer, such as 120.121.123.124.

Therefore, with the increase of computers connected to Internetwork, their number of available IP addresses is predicted to be exhausted only in a short period of time. For this reason, IPv6 has been introduced.

IPv6, also referred to as IPng (or IP Next Generation), is an upcoming version of the IP address system. (IPv5 was the experimental version used primarily for streaming data.) As we know IPv4 uses 32-bit addresses, IPv6 uses 128-bit addresses, Which increases the number of possible addresses by an exponential sum.

For example, IPv4 allows us to use 4,294,967,296 addresses (2 ^ 32), and IPv6 allows us to have more than 340,000,000,000,000,000,000,000,000,000,000,000,000 IP addresses. This should be enough for some time.

Because IPv6 allows a lot more IP addresses than IPv4, they themselves are more complex. They are usually written in this format: hhhh: hhhh: hhhh: hhhh: hhhh: hhhh: hhhh: hhh.

Each “hhhh” section has a four-digit hexadecimal number, which means that each digit can be from 0 to 9 and from A to F. An example IPv6 address can be identified as. F704:0000:0000:0000:3458:79A2:D08B:4320.

IPv6 Advantages:-

  • Increased Capacity: of address space resources are efficiently allocated to accommodate additional web server addresses.
  • Efficient Routing: allows for easy aggregation of prefixes assigned to (IP) internet protocol all networks.
  • Efficient Data Flow: enables the largest data packets to be sent simultaneously helping to conserve bandwidth.
  • Security: is improved due in part to improved authentication methods built into network firewalls.

Disadvantages of IPv6:-

  • Conversion: IPv4 is still widely used and the world is slow to convert to IPv6.
  • Communication: IPv6 machines cannot communicate directly to each other, in the very rare circumstance that they would need to.
  • Transition: The process of making the switch to IPv6 from IPv4 is slow and tedious.
  • Readability: Understanding IPv6 subnetting can be difficult on its own, let alone trying to remember/memorize your IPv6 address.

IPv4 addresses are binary numberIPv6 addresses are binary number
IPv4 addresses are the 32-bit IP addressIpv6 addresses are the 128-bit IP address
