In “automatic” tunneling, hybrid IPv4/IPv6 addresses are created by extending 32-bit IPv4 addresses to 128 bits by adding leading zeros. IPv6 packets are encapsulated within IPv4 headers, so that one ...

The IPv6 transition in your organization, more likely than not, involves bringing IPv6 into a mix that also includes IPv4. Here’s a look at what that means and how to make it work. The original title ...

The world is running out of IPv4 addresses – the familiar 32-bit numerical addresses used to represent the identity of every Internet-connected device in the world. The African Network Information ...

Michael Fry receives funding from ARC. If you’re the sort of person who relies on the internet every day, you’ll maybe have twitched slightly on hearing rumours that the world is running out of ...

Twenty years ago, the fastest Internet backbone links were 1.5Mbps. Today we argue whether that’s a fast enough minimum to connect home users. In 1993, 1.3 million machines were connected to the ...
