RIPE Atlas can now test packet flows from more than 1000 vantage points on the Internet. We took a quick look at anycast traffic to DNS root name servers. There is a lot of interesting signal in this data.
In this article, we report about a one-day measurement of the RPKI and BGP infrastructure.
Since the RIPE NCC launched its Resource Certification service, there is a steady increase in the number of prefixes covered by certificates.
In this article we will be delving into the behaviour of the Linux implementation of TCP, and looking at the way in which TCP establishes a connection. There are socket options in Linux that cause the TCP handshake to behave in a rather curious way.
RIPE Atlas provides a view of 188.8.131.52/16 from the data plane. Can packets actually get there and back? Please find the results in this article.
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.
During RIPE 63 in Vienna, a few of us got together and started downloading, compiling and configuring the RPKI daemon. I now set up two routers which I made publicly available. The details are described in this article.
In this article we describe how we use RIPE Atlas to determine which instance of a name server a probe uses.
This article describes a technical design for the introduction of abuse contact details in the RIPE Database and streamlining the general approach to handling contact details.
