Final Five IPv4 Blocks Allocated

Thursday, February 3rd, 2011

As anticipated, the final five /8 blocks of IPv4 addresses were allocated from IANA to the RIRs this morning. They were apparently granted in alphabetical order.

102/8    AfriNIC    2011-02    whois.afrinic.net    ALLOCATED
103/8    APNIC      2011-02    whois.apnic.net      ALLOCATED
104/8    ARIN       2011-02    whois.arin.net       ALLOCATED
179/8    LACNIC     2011-02    whois.lacnic.net     ALLOCATED
185/8    RIPE NCC   2011-02    whois.ripe.net       ALLOCATED

Predicted RIR IPv4 Exhaustion

Tuesday, February 1st, 2011

Geoff Huston was kind enough to produce a graph of the month-by-month probability of when each RIR will run out of their “normal” IPv4 address pool. As he described in a post to NANOG, this graph assumes that no unusual inter-region activities cause the utilization rate to change. So, things could go differently in reality. But this is a pretty good starting perspective on when member organizations will start being denied new IPv4 address allocations.

IPv4 Exhaustion is Here

Monday, January 31st, 2011

Today the last “normal ” IANA allocation of IPv4 addresses was made to APNIC.  (See the announcement at http://www.apnic.net/publications/news/2011/delegation.) APNIC received the following two /8 network blocks:

  • 39/8
  • 106/8

By a quick view of the IANA registry at http://www.iana.org/assignments/ipv4-address-space/ipv4-address-space.xml, I can see that there are now five blocks remaining. Per the rules agreed upon by IANA and the five RIRs, these will soon be distributed so that each of the RIRs will receive one more /8. The remaining blocks are:

  • 102/8
  • 103/8
  • 104/8
  • 179/8
  • 185/8

In other words, IPv4 exhaustion is here – the IANA supply is gone, the RIR supply is limited, and soon organizations will be unable to acquire more network space.  This is going to be an interesting year (and decade).

Religion versus The Economy

Monday, September 20th, 2010

I’m not sure what *precisely* should be understood after looking at this chart, recently published in Religious Outlier by Charles M. Blow. At the very least it suggests that there is an inverse relationship between Religion and Wealth, with the US being a potential outlier. There are a number of problems with assuming causation, either that wealth leads to decreased religion or that religion leads to poverty, but my gut suggests both could be true. I’d like to see a better statistical study of this, but in the meantime:
