In the ever-evolving landscape of internet technology, the exhaustion of IPv4 addresses has become a critical concern. With only approximately 4 billion IPv4 addresses available, the growing number of connected devices and advancements in networking technology have begun to strain this limited resource. IPv4, or Internet Protocol version 4, uses 32-bit addressing, providing a fixed pool of unique IP addresses. This limitation becomes increasingly apparent as more devices—smartphones, tablets, laptops, IoT devices, and autonomous vehicles—access the internet. Each device requires a unique IP address to communicate effectively within networks. ...

The Oslo Opera House is a special landmark. Next to the central station, in the Oslo Fjord lies this white monument where modern architecture meets nature.

On the sandy beaches of The Netherlands lies Kijkduin, a place near The Hague. Early spring it was a bit windy and sunny.

IPv4 (now) and IPv6 (now and future) make it possible to connect devices to the internet. With the original design of the net every device received a unique address to communicate with other devices. When the internet grew the demand of addresses grew as well. We are now in the situation that there are no more free addresses, so new devices can’t connect to the net, without recycling existing addresses. That doesn’t sound too bad at the moment, but will become a big problem when there are really no more free addresses available. ...
