FW: IP Address utilization of The LIRs
Dear all, There was a question probably from Daniel that he asked what LIR want to see on stats web page. As a LIR, I want to see IP address utilization for my AS when I query my AS from stat web site. It would be very nice if we get this information per prefix level. I think we can achieve this using netflow (without using confidential information) information. We can tell each LIR to send netflow data (only source,destination address and AS information. No protocol,port & traffic information to avoid confidential data) to distributed RIPE netflow servers. In the MAT-GW presentation, Arbor Atlas presented that they are getting hourly data from 129 different provider. I think we can use this information as well to find exact utilization of the IP Address space of each AS. I'm looking forward to go for IPv6 in my network as well but there is fact that most of the network, access devices doesn't support IPv6 yet. So there is still big demand for IPv4 and I'm sure we have some LIR that they are less than %50 utilization of IP Address. We can take this IPs from these LIRs if they don't have a plan to use this addresses recently and give it to LIRs which they are really need this. This will more give a time to world to move IPv6.

We have a documentation for that.

We wouldn't like that and I personally think it wouldn't scale.

We (ACOnet, AS1853) also host an Arbor Atlas box. Maybe I misunderstand how it works, but in our case, we only route currently not used ip prefixes to the box and it does all the magic. No netflow records where exported to Arbor Atlas. Maybe someone from Arbor can correct me if I'm wrong?

That won't work either and would lead to an explosion of the IPv4 routing-table - in my opinion. Use IPv6 - the sooner the better. regards from Amsterdam, Harald
This will more give a time to world to move IPv6.

For your own AS, your internal records should tell you how much space you have assigned, and your own equipment should give an indication of how much of each assignment is actually in use (how accurate this can ever be is left as an exercise for the reader)
In the MAT-GW presentation, Arbor Atlas presented that they are getting hourly data from 129 different provider. I think we can use this information as well to find exact utilization of the IP Address space of each AS.
As of May this year, there are over 37k ASes in the routing system, announcing over 360k prefixes. I never like to say that anything is impossible, but this task (although interesting) would certainly be very hard.

From the MAT perspective, I think that identifying used vs. unused addresses is of notional interest, but I don't believe it's within the means of the RIPE NCC to collect that data regionally, let alone globally.
The concept behind RIPEstat does fully support using third party datasets (where permitted), and we'd be happy to add a plugin to expose this if the dataset owner permitted. On the topic of reassigning unused v4 space to needy LIRs, I'll point you towards the Address Policy WG http://www.ripe.net/ripe/groups/wg/ap Thanks for your suggestion, please keep these ideas flowing. If anyone else has opinions on this topic, do please share. Regards Mark -- Mark Dranse RIPE NCC
