Re: So, IPv4 addresses are like petroleum
Yes. In many ways they are like petroleum. There is a limited amount. Nobody is really sure when we will hit that limit but we have gotten far enough that there can be problems with the supply. Some groups control a massive amount for no good reason. Large parts of the world have next to none compared to their populations. There are replacements that might be useful if more people were to use them.
IPV6 has many problems, and making any change is difficult, but it is already chaotic to try to find and keep IPV4 addresses. This block may have reduced that pressure for a little bit, but in only one region of the world and only for so long. Given the aggressive CGNAT used in some parts of Asia, I imagine demand for these addresses will be fierce.
