Well as made pretty clear from the media recently, the shortage of IPv4 address space is getting close to 'no more' IPv4 address space. Within the past week, APNIC requested the last two available /8 networks to be distributed in its region. The five remaining /8's are now about to be distributed equally (per an ICANN policy) to each of the five Regional Internet Registries (RIRs), which are ARIN, RIPE NCC, APNIC, LACNIC, and AfriNIC.
Posted on the NRO website yesterday is note about a 'significant announcement' happening tomorrow (February 3, 2011) at 9:30am EST. They also mention that the event will be broadcast live over the Internet at http://www.nro.net/news/icann-nro-live-stream. It's pretty obvious that this is the event where the final 5 /8 networks are being allocated, as well as showcasing the dire need for IPv6 adoption.
Be sure to tune in to witness a pretty big piece of Internet history!
