The major change was of course the expansion of the size of the IP source and destination address fields in the packet header from 32-bits to 128-bits. There were, however, some other changes that apparently were intended to subtly alter IP behaviour. One of these was the change in treatment of packet fragmentation.…

BGP More Specifics: Routing Vandalism or Useful?
The Border Gateway Protocol (BGP) is the routing protocol that keeps the Internet glued together. The public Internet is composed of some 58,000 component networks (BGP calls them “Autonomous Systems” [AS’s]), many of which are very small, while some are very large both in terms of geographical coverage and numbers of users.…

BBR TCP
The Internet was built using an architectural principle of a simple network and agile edges. The basic approach was to assume that the network is a simple collection of buffered switches and circuits. As packets traverse the network they are effectively passed from switch to switch. …

Look Up!
Far from being a vibrant environment with an array of competitive offerings, the activity of providing so-called “last mile” Internet access appears to have been reduced to an environment where, in many markets, a small number of access providers appear to operate in a manner that resembles a cosy cartel, strenuously resisting the imposition of harsher strictures of true competition.…

Addressing in 2016
Time for another annual roundup from the world of IP addresses. Let’s see what has changed in the past 12 months in addressing the Internet, and look at how IP address allocation information can inform us of the changing nature of the network itself.…
