IPV6 – what do you have to consider?

The number of IP addresses on the Internet continues to grow. To properly support all of these devices, network administrators need to use the new Internet Protocol Version 6 (IPV6) change. In this Article Find out what you need to consider when using IPV6 and how you can use it efficiently.

What is an IPv6 address?

IPv6 is the new generation of Internet protocols and offers a number of improvements over IPv4. One of the most important improvements is the expanded addressing, which allows up to 2^128 devices to be addressed. This corresponds to approximately 3.4×10^38 addresses, providing a much larger address space than IPv4, which only supports 4.3×10^9 (or 4,3 billion) addresses.

What is an IPv4 address?

IPv4 addresses make 32-bit addresses, which consists of four octets (8-bit groups) consist. Each octet can take a value between 0 and 255. An IPv4 address is therefore typically in the form xxx.xxx.xxx.xxx, where xxx represents each octet.

What is the difference between IPv6 & IPV4?

IPv6 is the latest version of the Internet Protocol and offers a variety of improvements over IPv4. A key difference is that IPv6 supports more addresses – 2^128 compared to IPv2’s 32^4. This allows many more devices and applications to be connected directly to IP addresses, resulting in faster and more efficient communication. IPv6 also has improved security features that make it more difficult to intercept packets and leak information.

Switching from IPv4 to IPv6

IPV6 is the new version of the Internet and is being rolled out gradually. IPv4 is the current version that is still widely used. Switching from IPv4 to IPv6 requires some precautions and knowledge of the differences between the two protocols.

The first precaution that should be taken is to inventory the devices and services connected to the Internet are connected. This includes Desktop, smartphones, tablets, game consoles, webcams, printers and other network devices. Each of these devices needs to be checked whether it is IPv6 capable or not. Many modern devices already support IPv6, but older devices may need to be updated or replaced.

Another important step is to determine the current network setup and identify the configuration changes required to support IPv6. In addition, the necessary changes must be made to the Network infrastructure to make the transition to IPv6 easy.

A DNS update is also required so that all devices and services within the network can process the addressing correctly. Therefore, you should definitely hire a professional IT service provider to ensure the transition from IPv4 to IPv6 is effective.

What types of IPv6 are there?

IPv6 comes in two basic forms: solid and changeable. Solid IPv6 addresses are immutable and are often used for things like router or others Devices that require a permanent address are used. Most DesktopHowever, cell phones and other devices use a variable IPv6 address that can change over time.

What problem does IPv6 solve?

IPv6 solves the problem of IPv4 addressing, which will soon no longer be sufficient due to the increasing use of Internet devices.
IPv6 allows for a larger number of IP addresses because it is a 128-bit addressing system acts that more than 340.000.000.000.000.000.000.000 possible addresses offers (compared to the 4 billion addresses of IPv4). This is important to support real-time internet usage and with more devices, as well as connecting self-driving cars, medical devices, etc.

Security and IPv6

The switch to IPv6 is an important step towards future-oriented communication. While IPv4 addresses 32-bit networks, IPv6 allows addressing 128-bit networks. This additional bit length ensures an enormous increase in the number of addresses that can be generated and thus assigned. With IPv6, many more devices and users can be online at the same time without them disturbing or hindering each other.

IPv6 is not only a larger version of IPv4, but also brings some new ones security features with yourself. For example, this will be the case IPsec integrity check already stipulated in the IPv6 protocol specification. This can ensure that data cannot be changed or manipulated along the way. Also the so-called “IPv6 flow spec“ allows network administrators to protect services and applications on one side of the network from attacks.

Overall, IPv6 is a very secure way of communication that is suitable for all types of environments. However, it does not provide absolute protection against security threats. Therefore, network administrators should continue to take measures to secure their networks, such as firewalls or encryption techniques.

Advantages and disadvantages of IPv6

The advantages and disadvantages of IPv6 are manifold. First of all, the size of the address space is of course a big advantage. IPv6 has an incredibly large address space, theoretically up to 340 sextillion (340×1036) unique addresses. This is a huge improvement over the approximately 4,3 billion (4,3x109) addresses that IPv4 offers. In addition, IPv6 also enables better routable and QoS support.

Another key advantage of IPv6 is that Safety. Since each hardware address is unique in IPv6, attackers can no longer easily MAC addresses spoofing . In addition, IPv6 supports the IPSec encryption by default, which means that data packets are automatically encrypted, which is the Safety elevated.

Another plus is the support of Multicast transmissions. This means that a broadcast packet can be sent to multiple recipients at the same time instead of addressing each recipient separately. IPv6 also supports simplified configuration for DHCPv6 and autoconfiguration.

However, there are also some disadvantages of IPv6. One of the biggest is the high implementation effort and capital costs, as many network devices may not be compatible with IPv6 or may need to be replaced. Additionally, the transition period from the old IPv4 to IPv6 format may be difficult and costly.

The IPv6 guidelines and what does they mean?

The expansion of IP addresses by 6 bytes was driven by the need to support the growing Internet. In the past, connecting different IPv4 networks over the Internet repeatedly caused problems, so a new system was needed. IPv6 solves the addressing problem and dramatically increases the maximum number of users and devices that can be connected to the Internet. The switch to IPv6 is therefore inevitable and must be undertaken by all companies and organizations that currently rely on IPv4. Deutsche Telekom, for example, recommended it to everyone customersto switch to IPv2018 by 6 at the latest.

Conclusion on IPv6

IPv6 is the future generation of the Internet Protocol and offers a variety of advantages over IPv4. However, there are also some disadvantages that should be taken into account.

One of the most important questions is whether IPv6 is the right choice for your business. In many cases it is not necessary to switch to IPv6 immediately. However, there are some situations where it may make sense to implement IPv6.

First of all, it is important to understand what IPv6 is and how it works. IPv6 is the new version of the Internet Protocol and offers a number of improvements over the older IPv4 protocol. The main improvements of IPv6 are the expanded addressing capabilities and the improved Safety.
Switching to IPv6 is an important step in dealing with increasing Internet traffic volumes. Still, there are a few things you should consider before making the switch. First of all, you should make sure that all devices and services are IPv6 compatible. The security infrastructure must also be adapted to the new IP addressing. In addition, it is important to have enough IPv6 addresses - preferably more than you actually need. This is the only way to ensure that Network will continue to function smoothly in the future.
