NANOG Meeting Presentation Abstract

IPv4 Address Space Allocation and Usage Trends
Meeting:	NANOG22
Date / Time:	2001-05-21 1:30pm - 1:50pm
Room:	Forum Hall
Presenters:	Speakers: Scott Marcus, Genuity Scott Marcus is the Chief Technology Officer for Genuity Inc. He has a strong interest in network design, forecasting, and capacity planning, and specializes in the technologies and economics of internetworking transmission systems. When GTE acquired the former BBN, he led the engineering design teams that created the initial design for Genuity\'s wide area data network, incorporating SONET/DWDM, TDM, ATM, Frame Relay, Internet and voice/VoIP services.<BR> <BR> Scott has contributed to the architecture and design of large internetworking systems for commercial service providers, carriers, corporate customers, and the U.S. government. He has served in a wide variety of roles at Genuity and its predecessor organizations, including systems architecture and engineering, capacity planning, legal and regulatory advocacy, sales, business development, consulting, and product architecture and design. He is a trustee of the American Registry of Internet Numbers (ARIN), Vice Chair of IEEE CNOM, and author of Designing Wide Area Networks and Internetworks: A Practical Guide.<BR> <BR> The analysis of IPv4 address depletion described in this presentation was sponsored by the Regional Internet Registries (RIRs): APNIC, ARIN, and RIPE NCC.
Abstract:	IPv4 address space is critical to the operation of today\'s Internet, and exhaustion of the IPv4 address space was once thought to be likely in the mid-nineties. Nonetheless, few systematic studies of the rate of IPv4 depletion have been undertaken in the past five years. ARIN recently took the lead, with active support from APNIC and RIPE NCC, in establishing a small \"blue ribbon\" team to do quantitative analyses and forecasts of consumption of the identifiers that the RIRs (the Regional Internet Registries ARIN, APNIC and RIPE NCC) maintain, and to assess their impact on the global Internet, in support of policymakers in the RIRs and elsewhere. To that end, we are also working to standardize the format and semantics of RIR allocation data, and to make them available to other external researchers. The rate of IPv4 allocation seems for now to be contained to single digit percentage expansion per year, with the rate of increase declining over time in the Americas (i.e. negative second derivative). Growth in the Asia Pacific region is, not surprisingly, trending upwards, but starting from a lower base.
