Geoff Huston questions the goal of completely replacing IPv4 with IPv6. Thanks to CDNs and mobile traffic, address scarcity is no longer a major problem. If you talk to networkers about IPv6, there is ...

The global transition from IPv4 to IPv6 has gained major traction, driven by the urgent need to accommodate a rapidly expanding number of internet-connected devices and the introduction of IPv6 ...

In the early 1990s, internet engineers sounded the alarm: the pool of numeric addresses that identify every device online was not infinite. IPv4, the fourth version of the Internet Protocol, used ...

The Internet Protocol (IP) is the most widely used communications protocol. Because it is the most pervasive communication technology, it is the focus of hundreds of thousands of IT professionals like ...

It would have been so easy if the early Internet and TCP/IP network designers had made IPv6 backward compatible with IPv4. They didn't. In 1981, IPv4's 32-bit 4.3 billion addresses look more than ...

Word around the net is that there's a new website technology that allows for a faster, safer web browsing experience, and it's called IPv6. As it turns out, this protocol isn't new at all, but instead ...

Internet pioneer Huston questions the introduction of IPv6, which has provoked controversial reactions. Gert Döring weighs up pros & cons and advises: go for it Gert Döring has been working with IPv6 ...

Internet Protocol (IP) is the foundation of the internet, enabling communication between devices across the globe. Without an IP address, the Internet will simply not work because the data will not ...

Many IT people, who are unfamiliar with IPv6, believe the responsibility for IPv6 deployment falls on the network-teams. However, those who are knowledgeable about IPv6 realize the migration to IPv6 ...

It's been a quarter of a century since the first IPv6 standard was finalized as RFC 2460, and to say adoption has been slow is an understatement. The pool of available IPv4 addresses has been ...

If you are using Internet or almost any computer network you will likely using IPv4 packets. IPv4 uses 32-bit source and destination address fields. We are actually running out of addresses but have ...

We just saw that the mask determines where the boundary between the network and host portions of the IP address lies. This boundary is important: If it is set too far to the right, there are lots of ...
