Today's ARIN estimated depletion date:


APNIC hands out some IPv4

2010-07-01

Here is an explanation if you are curios why the predicted depletion date was moved to an earlier date all of the sudden. APNIC made some very large allocations yesterday.

  • China Mobile allocated a quarter of the 223/8 netblock. This equals about 4 million addresses and the addresses were in the range 223.64.0.0 – 223.127.255.255.
  • China Telecom allocated about 750 thousand addresses to the Shanxi province in the ranges 1.68.0.0 – 1.71.255.255 and 223.8.0.0 – 223.15.255.255. Additionally they allocated about half a million addresses to the MeiMengGu province in the range 1.180.0.0 – 1.183.255.255 a few days ago.
  • NTTDoCoMo in Japan allocated the range 1.72.0.0 – 1.79.255.255 or about ½ million addresses.

    For the love of $deity, _please_ use proper CIDR notation. The readers of this site are obviously technically inclined. Reading 223.64.0.0/10 is a lot simpler and faster than calculating from “one quarter of a /8″, “4 million addresses” or even “223.64.0.0 – 223.127.255.255″.

    Ideally, just make a list:

    $date: $assigner to $assignee – $ip_in_cidr ($count_ips)

    or

    $date: $ip_in_cidr ($count_ips) – $assigner to $assignee

    Thanks,

    Hi Richard and thanks for your comment,

    Admittedly I went a little bit over board with all the different ways of describing the size of the allocations in this blog entry. The quarter of a /8 was probably a bad idea. The background is that I wanted to illustrate the fact that China Mobile and China Telecom are allocating really large chunks of IPv4 address space. You sometimes hear people complaining about HP and Ford having legacy /8 blocks, but you never hear anybody complain about China Mobile having as much if not more space allocated.

    I don’t agree with you that all readers of this blog are all technically inclined. I get a lot of visitors via Google searching for IPv4 depletion. I have always been quantifying the allocation sizes with a number on top of the Range and/or CIDR notation to make it easy for anybody to see how fast we are burning IPv4 addresses. I will continue to do so, but I will take your suggestion and be more consistent about using CIDR notation.

    Thanks for the feedback!

    I think the “Distance between predictions” graph is broken. The tail has looked the same for quite some time, despite various jumps in both predictions.

    Hi Ty,

    Could be. I really need to improve the graphs here. Let me see if I can take a stab at it this weekend. (Bummer, I need to learn gnuplot)

    Just to clarify, the “distance between prediction” graph is just adding stuff on the right hand side, the tail will always be fixed. The interesting thing to pay attention to is if the distance gets lower on the right side of the graph.
