随着服务于全球IPv4地址空间需求的注册机构的免费地址池不断耗尽，稀缺已成为现实。需要地址空间的网络无法再从各自的注册中心获得更多的地址分配。
在这项工作中，我们框架的IPv4地址耗尽现象和相关问题的基本面。我们详细介绍了自IPv4标准化以来，IPv4地址空间的当前生态系统是如何演变的，从而导致我们今天面临的相当复杂和不透明的情况。我们概述了地址空间管理的演变以及地址空间使用模式，确定稀缺问题的关键因素。我们描述了可能的解决方案空间，以克服这些问题，并打开的角度来看，地址块作为虚拟资源，其中涉及的问题，如地址块之间的差异，资源认证的需要，以及网络之间传输地址空间时出现的问题。
With the ongoing exhaustion of free address pools at the registries serving the global demand for IPv4 address space, scarcity has become reality. Networks in need of address space can no longer get more address allocations from their respective registries.
In this work we frame the fundamentals of the IPv4 address exhaustion phenomena and connected issues. We elaborate on how the current ecosystem of IPv4 address space has evolved since the standardization of IPv4, leading to the rather complex and opaque scenario we face today. We outline the evolution in address space management as well as address space use patterns, identifying key factors of the scarcity issues. We characterize the possible solution space to overcome these issues and open the perspective of address blocks as virtual resources, which involves issues such as differentiation between address blocks, the need for resource certification, and issues arising when transferring address space between networks.
