You have probably already heard the news, but just to make sure no one is left
out of the loop, I am posting this note.
The last five /8 IPv4 address blocks were assigned today.
Two /8s were recently allocated to APNIC, which triggered the implementation of
the Exhaustion Phase set out in the Global Policy for the Allocation of the
Remaining IPv4 Address Space. Today in Miami, Florida in a very nice ceremony,
this policy was implemented, and each RIR received one of the final /8 address
blocks. As of now, there are no more unallocated IPv4 unicast /8s in the IANA
pool. The current status of the IPv4 address space can be seen in the IANA IPv4
Address Space Registry at:

We have all known that this day was coming for a long time. In preparation,
the IETF developed IPv6. IPv6 is ready, and it has been ready for a long time.
This milestone simply increases the urgency for IPv6 deployment. The
explosive growth of the Internet can only continue with the bigger address
space offered by IPv6.
The depletion of the IANA IPv4 address pool is not a crisis. Next week the
Internet will not be significantly different that it was a week ago. There
will not be any notable short-term effects caused by the empty IANA IPv4
address pool.
There is no crisis, but there is a need for action so that the Internet can
continue to grow. The transition to IPv6 requires the attention of many
actors. However, our parents, spouses, and children will be largely unaware of
the transition. They will continue to be amazed of the endless possibilities
offered by the growing Internet. For them, this milestone will remain
insignificant.
To the universal deployment of IPv6,
Russ
