IPv4 has lasted for decades because technologies such as NAT, private addressing, and Classless Inter-Domain Routing allowed more efficient use of its limited address space. These techniques enabled many devices to share a single public IP address, slowing address exhaustion. However, IPv4 uses a 32-bit address system that supports only about 4.3 billion addresses, which is insufficient for the rapidly growing number of internet-connected devices. Therefore, it is not sustainable in the long-term, leading to the adoption of IPv6 with a much larger address space.

This is due to the introduction of NAT which allows many devices in a private network to share one public IP address.
