Threat actors are increasingly operating in the IPv6 plane, and you don't have the ability to see that activity unless you enter that plane and start observing. You need to start learning and expanding your management capabilities to cover not just IPv4, but IPv6 and other planes.
Real vulnerabilities and threats
Many versions of Linux and Windows now favor IPv6. Additionally, embedded versions of Linux are common in IoT devices, and these devices are becoming increasingly common in various environments. If you are not working on this plane, when these IoT devices come to your network asking for an IPv6 address, you may not even know it. It is not uncommon for organizations to have a significant number of these rogue devices that are generally unmanaged, creating risks.
IoT devices are also typically not updated because cyprus mobile database are either unpatched or patched in questionable ways. Threat actors have the ability and capability to spoof IPv6 addresses and hijack these devices, rerouting traffic as they see fit. Obviously, devices in an organization cannot be trusted, so it is necessary to ensure consistent DHCP and DNS control across the IPv6 network.
Many organizations try to avoid IPv6 as long as possible due to the extensive and complex training required for network engineers. Instead, they rely on Network Address Translation (NAT). Unfortunately, NAT becomes inconvenient in environments where broad availability is required, such as MSP environments, some other management domains, or carrier-class networks.
Since IPv6 usage will inevitably grow, now is the time to acknowledge that you have or will soon have IPv6 on your network and start working with the IPv6 plane to incorporate it into your management strategy.
Recommendations for the transition to IPv6
Start by setting up a standard IPv6 DNS to help regulate traffic. Then deploy a fully IPv6-aware automation platform on the management network that you will use for monitoring, observability, and configuration management or automation. These two steps ensure that IPv6 routing works properly on all Linux and Windows devices and routers at the network level.
If you have a network automation platform, you have the tools to solve common and important problems, including:
