The Sky Still Hasn’t Fallen — Further Thoughts On IPv6

Just over a year ago, I wrote a piece on why IPv6 has not taken off. 12 months on, has much changed? To a greater extent, the urgency behind why IPv6 has to be adopted has grown – as mentioned in this piece pulling out the difference between the IoT and the IoE, the growth… Read More

How Should You Be Thinking About Your WAN?

For a twenty year period that began in the mid-1980s the enterprise WAN went through a series of transitions, starting with Time Division Multiplexing (TDM) based on T1 access and then moving on to Frame Relay, ATM, and finally to MPLS. Unfortunately, over the last decade there hasn’t been a new transmission service introduced into… Read More

The Sky Still Hasn’t Fallen — Further Thoughts On IPv6

Just over a year ago, I wrote a piece on why IPv6 has not taken off. 12 months on, has much changed? To a greater extent, the urgency behind why IPv6 has to be adopted has grown – as mentioned in this piece pulling out the difference between the IoT and the IoE, the growth of devices that are not under your direct control will mean that it becomes increasingly difficult to use IPv4 and network address translation (NAT) to meet the needs of an end-to-end mass device network. State of the nations… This interactive table on the RIPE NCC website shows that fewer than 20% of all networks with a registered autonomous system number (carriers … Read More
