We partnered with several Regional Internet Registries (RIRs), including the RIPE NCC, to examine what traffic is going to unallocated IP address ranges. In this particular case, we looked at traffic going to 5/8 and 37/8.

Roma Tre University presents three analyses related to the recent events in Egypt, proving interesting behavior in relation to the observed disconnection. We use tools like BGPlay and iBGPlay, developed for the visualisation of BGP dynamics.

In the routing graphs produced by the RIPE REX tool, we can get a different visualization of Egyptian networks falling off of the Internet, and observe some interesting phenomena.

After 3 updates and a lot of progress on IPv6 in general, it is time to think about the next version of the IPv6 CPE survey. With an increased deployment of IPv6, we are seeking a way to make it easier for you to provide feedback and to present the data in a more structured way.

For 20 years, the RIPE NCC counted the number of hosts in its service region. The Internet has grown dramatically since then and there are various ways to measure that growth. The article below describes the history of the Hostcount, the challenges we faced over the years and the reasons why we int…

In January 2011, the RIPE NCC will announce the production launch of the resource certification system. We made some extensions to the BGP beacons which we provide as a part of the Routing Information Service to assist network operators.

Last month we published a graph that shows how complete the RIPE Routing Registry really is. How many of the organisations that receive an Autonomous System Number (ASN) from the RIPE NCC use the RIPE Routing Registry to register their route objects. The results were encouraging. But do these route…
