The prefix 128.0/16 is filtered in Juniper devices up to and including JUNOS software version 11.1. We looked at three ways to get a rough estimate on how much filtering of 128.0/16 is going on on the Internet.

The introduction of a second IP protocol into the Internet presents many technical issues, and in previous columns we've explored many of the issues related to network engineering and infrastructure. In this column I'd like to head upward in the protocol stack to the rarefied air way up there at th…

Often when looking at IPv6 deployment statistics, the size of the organisation or the network is not taken into account. In this article, we look at IPv6 deployment of Local Internet Registries (LIRs) per country in correlation with the size of the LIR.

In this article we look at two "Happy Eyeballs" implementations, that aim to reduce degraded user experience as the result of broken dual-stack configurations. We call this degraded user experience "Unhappy Eyeballs". The Chrome web browser implementation seems to succeed in this aim, while Apple's…

According to address policy, the experimental address allocations for RIPE RIS beacons have to be returned soon. This would mean we have to either discontinue the RIS beacons or request permanent allocations for them according to address policy. We are asking for community support to continue opera…
