Introduction – There are now two versions of the Internet Procedure (IP): IPv4 and IPv6. Both types enable online network and data exchange, but the two versions identify devices otherwise and offer distinct features. So, which one is better, quicker, and more secure? This article offers a head-to-head contrast of IPv4 and IPv6, the two current available IPs for steering traffic across the Internet. Read on to learn the main difference between the two procedures and see why switching to IPv6 harms the long-term health of the Internet.

Internet Protocol (IP) is a numeric address allocated for every device linked to the Internet network. It is like the telephone number, a sole mixture of numbers that allows users to communicate with others. An IP address is accountable for two primary meanings. First, an IP enables users to be recognized on the internet. Additionally, IP addresses allow computers to send and receive material (in other words, communication) over the internet.

What is IPv4?

What is IPv4?

It is the following group Internet Protocol (IP) address standard envisioned to supplement and eventually replace IPv4, the protocol many Internet facilities still use today. Every computer, mobile phone, home automation constituent, IoT sensor, and any other device linked to the Internet needs a numerical IP address to connect with other devices. The original IP address system, called IPv4, is running out of address due to its widespread usage from the propagation of so many connected devices.

How Do IPv4 and IPv6 Work?

The 128-bit in the IPv6 address is eight 16-bit hexadecimal blocks detached by colon. For example, 2dfc:0:0:0:0217:cbff:fe8c:0.

IPv4 addresses are divided into “classes” with a Class A network for a few vast networks, a Class C network for thousands of small networks, and a Class B in between. IPv6 uses subnetting to adjust network sizes with a given address space project.

IPv4 uses class-type address space for multicast use ( IPv6 uses an integrated address space for multicast at FF00::/8.

IPv4 uses a “broadcast” address that forces each device to stop and look at the packet. IPv6 uses multicast groups.

IPv4 uses as an unspecified address and class-type address ( for loopback. IPv6 uses:: and::1 as unnamed and loopback address consistently.

IPv4 uses globally unique public addresses for traffic and “private” addresses. IPv6 uses internationally unique unicast addresses and local addresses (FD00::/8).

The advent of IPv6 brought more functions in addition to more IP addresses. For example, IPv6 supports a multicast address, allowing bandwidth-intensive packet movements (such as multimedia streams) to be sent simultaneously to multiple destinations, plummeting network services. But is IPv6 improved than IPv4? Let’s find out.

IPv6 has a new feature called auto information, which allows a device to produce an IPv6 address as soon as it powers up and places itself on the network. The expedient begins by looking for an IPv6 router. If one is present, the device can make local and globally routable addresses, allowing access to the broader internet. In IPv4-based networks, adding devices often has to be done physical.

IPv6 allows devices to stay connected to numerous networks simultaneously. This is due to interoperability and configuration competencies that enable the hardware to assign multiple IP addresses to the same device automatically.

Why Support IPv6? Benefit of

IPv4 (Internet Protocol version 4) is the 4 review of the Internet Protocol and the replacement to IPv4. It functions similarly to IPv4, providing the unique IP addresses essential for Internet-enabled devices to communicate. However, it does have one crucial difference: it utilizes a 128-bit IP address.

Key benefits of IPv6 include:

  • No more NAT (Network Address Translation)
  • Auto-configuration
  • No more private address collisions
  • Better multicast routing
  • Simpler header format
  • Simplified, more efficient routing
  • Genuine quality of service (QoS), also called “flow labeling.”
  • Built-in authentication and privacy support
  • Flexible options and extensions
  • Easier management (no more DHCP)

IPv4 uses a 32-bit speech destined for its net address. That means it can care for 2^32 IP addresses in total, around 4.29 billion. That may appear like a lot, but all 4.29 billion IP speeches have now been assigned, leading to the current scarcity issues.

Which Use of IPv4?

There is no simple answer to which to use: IPv6 or IPv4. IPv6 addresses are vital when we are thinking about the future. Even if there are ways to use an IPv4 address when we are already out of a unique address, these options can slightly affect the internet’s speed or cause other issues. Also, IPv6 may want to develop new technology and products. IPv6 is not strikingly faster than IPv4, but wholly changing from IPv4 to IPv6 would give the internet a vastly larger unique IP pool. So why are we motionless using IPv4?

The tricky part is that IPv4 and IPv6 communicate with each other. This is why the addition and adaptation of IPv6 are complex. The majority of websites or applications only support IPv4 type of IP address. Imagine suddenly changing the IP address of each device. Users would be unable to access most of the websites or requests, and we would have a massive mess on the internet.

Difference between of IPv4 and IPv6

Difference between of IPv4 and IPv6

Both type of IP address, IPv4 and IPv6, for user ID and messages between different plans over the net. IPv4 is a 32-bit IP address, though IPv6 is a 128-bit IP address. IPv4 is a number address, and dots distinguish its numbers. IPv6 is an alphanumerical address, and colons separate it.

We covered IPv4 and IPv6 types unconnectedly in detail. Now, we can compare these types and determine the main differences between these two protocols. We single out eight main differences between IPv4 and IPv6.

  1. Type of address: IPv4 has three different types of address of multicast, transmission, and unicast. IPv6 also has three types of addresses: anycast, unicast, and multicast.
  2. Packet size: For IPv4, the minimum pack size is 576 bytes. For IPv6, the most diminutive pack size is 1208 bits.
  3. Number of Header Arenas: IPv4 has 12 header arenas, though IPv6 supports eight.
  4. Optional fields: IPv4 has option fields, while IPv6 does not. However, IPv6 has a Postponement Header, which allows the protocol to extend in the future without moving the main packet structure.
  5. Shape: In IPv4, a newly installed system must arrange before communicating with other systems. In IPv6, a shape is optional, which allows choosing contingent on the required functions.
  6. Security: In IPv4, security depends mainly on websites and applications. It was not developed for security. IPv6 has integrated Internet Procedure Security (IPSec). Network security is not an option, as with IPv4, it is mandatory.
  7. Compatibility with mobile devices: IPv4 is unsuitable for mobile networks because, as stated earlier, it uses dot-decimal notation, while IPv6 uses Costa Rican colon. IPv6 is better and excellent for mobile devices.
  8. The main feature: IPv6 allows direct addresses because of the many possible addresses. However, IPv4 is previously widely feast and supported by many devices, which makes it easier to use.

How to Protect your IP address?

Why protect your IP address? With your IP address and location show, you expose yourself to a diversity of security and privacy issues, such as:

Packet sniffing: Hackers can witness your IP traffic, in a repetition known as sniffing, to discover sensitive information about you, such as your online bank activity.

Surveillance: Your ISP, snoops, and government can spy on your web traffic.

Geo-blocking: Websites can see your location and favor against you based on it. They can block gratified and even increase amounts.

Avast Secure Line VPN skins your IP address and anonymizes your online action to keep you harmless. Take back your online privacy in just one tick.

ThousandEyes Support for IPv6

ThousandEyes Support for IPv6

With IPv6 becoming more prevalent in cloud breadwinners and consumer access networks, you may previously be on the path to IPv6 placement with your network and requests.

If you are looking to understand IPv6 in your setting, there are three things you should be nursing:

  • IPv6 DNS resolution
  • IPv6 traffic paths
  • IPv6 BGP prefixes and routes

Thousand Eyes supports IPv6, so organizations can utilize IPv6 crossways in all their test types (web, network, voice, routing) and manager types (cloud, enterprise, endpoint).

Conclusion – IPv4 is the future of IP addresses. However, the process of whole change is long and complicated. If you are curious about using an IPv6 address, combining its usage with IPv4 is recommend because mainstream websites and requests still only support IPv4 addresses. The grouping of IPv4 and IPv6 use is called Dual Stack. In this article, we will look deeper into two types of IP addresses: IPv6 and IPv4. We will cover their difference and debate the predicted future of IP addresses.
