    IPv4 uses a 32-bit address space, which only provides about 4.3 billion addresses. With the explosion of smartphones, IoT devices, and always-on satellite connections (like Starlink), the world has officially run out of new IPv4 addresses.

    I understand that CIDR uses prefix lengths like /22, but how exactly does that prevent the waste we saw in Class B addressing?
