CIDR 2025 is the term used to refer to the projected exhaustion of IPv4 addresses by the year 2025. IPv4 addresses are the numerical labels assigned to devices connected to the internet, and they are essential for communication between devices. The exhaustion of IPv4 addresses is a serious concern because it could lead to a shortage of IP addresses and make it difficult for new devices to connect to the internet.
To address this issue, the Internet Engineering Task Force (IETF) developed IPv6, a new version of the Internet Protocol that uses 128-bit addresses instead of the 32-bit addresses used by IPv4. IPv6 provides a much larger address space than IPv4, and it is expected to eventually replace IPv4 as the standard for internet addressing. However, the transition to IPv6 has been slow, and many devices still rely on IPv4. As a result, there is concern that the exhaustion of IPv4 addresses could have a significant impact on the internet.
