• In February 2011 IANA (Internet Assigned Numbers Authority) depletes it’s free pool of IPv4 addresses and the RIR (Regional Internet Registries) have started to run out of IPv4 addresses as well.
  • As a result, on February 3 2011, IANA allocated the remaining /8 blocks to the RIRs.
  • From that moment the European RIR, called RIPE (Reseaux IP Europeens) decided that only the new LIRs (Local Internet Registry) will be eligible for a one-time /22 IPv4 allocation (1024 IPv4 addresses).
  • The slow transition to IPv6 and the possibility for a dual-stacked world for the foreseeable future, means that there is a continual need for IPv4 addresses.
  • As the available supply of IPv4 addresses dwindles, the market for this virtual commodities is heating up.
  • In 2011, when Microsoft paid $7.5 million for 666,624 IPv4 addresses as part of the Nortel bankruptcy (11.25$/IP), observers wondered whether this development would rush in the era of the commercial sale of IPv4 address space. As statistics from European registrar RIPE show, the market may have had a slow start, but we’re in that new era now.
