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.
What happens to BGP traffic when an announcement or withdrawal of an address prefix propagates through the Internet? See below some interesting graphs and observations.
The LIR Locator tool has been updated. It now contains a number of new options and features, including information about Local Internet Registries (LIR) with 4-star IPv6 RIPEness. The tool is mostly targeted to the members of the RIPE NCC, but also contains a public map accessible to everyone.
How do we know which addresses are still unallocated or unassigned? Find below a proposal to include unallocated address space in the statistics files the Regional Internet Registries publish daily.
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.
With IPv4 depletion imminent, we're keeping a close eye on allocation rates. In the article below you can see the IPv4 address allocations rates over time in all regions.
We have been using the prototype RIPEstat toolbox to analyse what happened to the Internet in Egypt.
This article summarises the first RIPEstat demo session that took place today, 25th January 2011. At the end of the article are the dates of the next demos, and options for providing feedback.
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.
Based on new information we received since the last publication, we updated the IPv6 CPE matrix below. Please also note a call for help. We are preparing a detailed survey to gather more user feedback and would like you participate in this survey.
