MUST READ: The World in Which IPv6 Was a Good Design

A lot of people are confused about the roles of network layers (some more than others), the interactions between MAC addresses, IP addresses, and TCP/UDP port numbers, the differences between routing and bridging… and why it’s so bad to bridge across large distances (or in large networks).

I tried to explain most of those topic in How Networks Really Work webinar (next session coming on April 2nd), but as is usually the case someone did a much better job: you MUST READ the poetic and hilariously funny World in which IPv6 was a good design by Avery Pennarun.

Cities like Los Angeles, Chicago, Brooklyn, and San Francisco have all experienced little or no disruption. New York City,  now the epicenter of the virus in the U.S., has seen a 24% dip out of its previous ten-week range. However, with a new median speed of nearly 52 Mbps, home connections still appear to be holding up overall.”To read this article in full, please click here
