However, the barrier to outer space was eventually broken in 1942, when Germany launched the V2 missile. Breaking Network Connectivity BarriersThe packet-based internet was a fundamental shift over switched-circuit telecommunications networks. Over the years, networking engineers have created solutions and workarounds like NAT (network address translation) due to the shortage of IP addresses and endless firewall rules -- to overcome network security and scalability challenges. A Network Barrier BreakthroughTo break through any barrier, there needs to be a significant technology impetus that makes the impossible actually possible. The IP address barrier has finally been broken by a simplified, scalable and secure environment via micro-segmentation.
