This new RIPE Labs article talks about trying to send large packets over the Internet. Above a certain size, these packets will have to be fragmented, which is known to cause problems. In both IPv4 and IPv6, we see approximately 10% of RIPE Atlas probes that are unsuccessful in pings with fragmented packets, while they don't encounter problems with smaller unfragmented packets. … Read more

It's not the case that every single address is being used by an active device.… Read more

Visualising Bandwidth Capacity and Network Activity in RIPEstat Using M-Lab Data
Visualising Bandwidth Capacity and Network Activity in RIPEstat Using M-Lab Data
Vasco Asturiano — 09 Sep 2013

As a result of the cooperation between the RIPE NCC and Measurement Lab (M-Lab), you can now visualise the bandwidth profiles and network activity of IP prefixes and individual countries. This is provided as RIPEstat widgets using data collected by the M-Lab platform. See below for details about the measurement methodology and relevant use cases.… Read more
