The IANA IPv4 free pool was exhausted today, 3 February 2011. Each of the Regional Internet Registries (RIRs) has now received one of the final five /8s. The RIPE NCC has been allocated 185/8.
The RIPE NCC is holding reserves totaling approximately four /8s (around 75 million individual IPv4 addresses), not including 185/8.
RIPE will most likely exhaust their reserves sometime in 2011:
As we unable to anticipate consumption rates, we cannot fully predict how long our reserves will last. However, we would like to reassure you that our supplies will not be exhausted within the coming months.
