A press conference taking place on Thursday in Miami is expected to mark the last allocation of Internet Protocol, Version 4 addresses by the central authority that assigns them.
The event, which will take place at 9:30 a.m. Eastern time and be shared via webcast, will bring together four nonprofit organizations that coordinate the Internet’s addressing system, according to an advisory sent to media on Tuesday. The Internet Corporation for Assigned Names and Numbers (ICANN), the Number Resources Organization, the Internet Architecture Board and the Internet Society all are scheduled to participate.
Once the RIRs get those final blocks, they will be able to keep assigning addresses to local enterprises and ISPs but won’t be able to go back to IANA for more. Under these conditions, some RIRs are expected to tighten their own rules for handing out addresses. The Asia-Pacific Network Information Center (APNIC), which earlier this week received two /8 blocks from IANA, has said each of its account holders will only be eligible for one more minimum-sized allocation. APNIC thinks those allocations can continue for about five years. It will hold one smaller block in reserve during that time.
