Caidagram is a tool developed at CAIDA (the Cooperative Association for Internet Data Analysis). It allows the user to visualise geographically-based measurements about the Internet, focusing on trends and variations over time.
This article summarises the second RIPEstat demo session that took place today, 22 February 2011.
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.
Last year, in a series of two articles, we presented statistics on the number of RIPE NCC members and the resources distributed to our members. With twelve months passed, we revisit the topic and look at how things evolved in 2010.
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.
