Today, Network Address Translators (or NAT) devices are everywhere. Their rapid rise towards universal adoption was not part of a planned effort. Instead, it was fueled by the continued growth of the internet and the corresponding depletion of the IPv4 address space. Besides obvious advantages, such as IP address reuse and hiding of internal network topologies, NAT technology has some important drawbacks as well. This blog post takes a closer look at these downsides.
The internet is still expanding. Even more, we're facing a major explosion of the number of devices connected to the internet. The rise of smartphones, wearables and the Internet of Things are evolutions that will expand the number of connected devices to numbers unseen so far. The transition to IPv6 is inevitable, but why does it seem to take so much time?
This blog post helps you solve common issues you may encounter when testing Network Address Translation (NAT) routers, or devices behind NAT routers.
