Yesterday, ARIN announced the depletion of their IPv4 address pool. They join APNIC and RIPE in no longer being able to provide IPv4 addresses by traditional means.
Allocation of IPv4 addresses in future will be strictly limited. A small number may be allocated to those who meet the criteria from a final /8 block reserved for the period of transition to IPv6. If you can justify a requirement then you will receive a single /22 which represents only 1024 addresses. The alternative is obtaining IPv4 addresses through the transfer process.
The only long term solution for Internet users is the transition to IPv6.
IPv6 provides a huge address space and many improvements over IPv4. A key improvement is that IPv6 removes the limitations placed on the IPv4 Internet by having to preserve IPv4 addresses through address sharing (CGN and NAT). This makes possible innovative applications and potential improvements in performance.
Today large parts of the current Internet are IPv6 enabled. Most of the major content providers are IPv6 enabled (over 50% of the world’s top web-sites) and users with both IPv4 and IPv6 find that the majority of their traffic is carried over IPv6 (70+%).
In addition, IPv6 provides the address space and functionality required by the Internet of Things (IoT). IPv4 has never been an option for supporting IoT.
