What are the stages of IPv4 exhaustion?
There are three key stages in the process of IPv4 exhaustion: Stage 1: The Internet Assigned Numbers Authority (IANA) will run out of unused IPv4 address space to allocate to the five RIRs Stage 2: The RIRs will run out of unused IPv4 address space to allocate to their members Stage 3: Local Internet Registries (LIRs) that are using IPv4 space already allocated to them from the RIRs will run out of unused IPv4 address space to assign to their customers (End Users) The RIPE NCC will keep its members and the RIPE community informed during every stage of IPv4 exhaustion.
