BeyondCounting! New Perspectives on Active IPv4 Blocks Buying

2. Beyond Counting! New Perspectives on Active IPv4 Blocks Buying The internet faces a fundamental resource scarcity issue: the Internet Assigned Numbers Authority (IANA) exhausted its pool of available IPv4 blocks to buy in 2011. As of 2018, also four out of five (APNIC, RIPE, LACNIC, ARIN) of the Regional Internet Registries (RIRs) have run out of freely available IPv4 blocks to buy. The exhaustion of readily available IPv4 blocks to buy puts increased pressure on both ISPs and policy makers around the world. ISPs need to find open-ended ways to accommodate the needs for IPv4 connectivity of their customers. Policy makers need to establish regulatory guidelines for the emerging marketplace for IPv4 blocks to buy. • As the internet continues to expand, effective governance and administration of the IPv4 blocks to buy is critical to supporting and maintaining infrastructure and services, and to ensure further sustainable growth of the internet while managing the simultaneous, increased adoption of IPv6. Monthly client IPv4 blocks counts had shown constant growth up to 2014, but since then, the IPv4 count has stagnated while IPv6 counts have increased. Since 2014, the CDN observes a relatively constant number of active IPv4 blocks to buy. However, the analysis show significant churn and volatility in active IPv4 blocks; the set of active IPv4 blocks can vary by up to 25% during a year.

3. By looking across the active addresses in a prefix, it is possible to identify and attribute activity patterns to network restructurings, user behaviors, and address assignment practices. Finally, by combining spatio-temporal measures of address activity with measures of traffic volume and sampling-based estimates of relative host counts, the study yields detailed insights on worldwide IPv4 spaces utilization, including empirical observations of under-utilization in some areas and complete utilization, even exhaustion, in others. The degree of utilization is correlated with the addressing mechanisms that network operators use and varies substantially across geographic regions, administered by the five regional internet registries.

4. IPv4 Blocks Buying Activity: Breakdown per Regional Internet Registry The team’s findings have a number of significant implications, from measurement practice, to internet Governance, network management, network security, and content delivery. Keep points in the paper are as follows: Implications to Measurement Practices: At the time of the research, activity from 1.2 billion globally-unique IPv4 blocks for sale was measured, which is the highest number ever reported based on measurements. The address count analysis suggests that remote active measurements are insufficient for census or complete survey of the internet, particularly at IP address-level granularity. The passive measurements show extensive churn in IPv4 blocks buying across all timescales which implies that any census needs to be qualified by the observation frequency and period. • Implications to Internet Governance: • The 1.2 billion active IPv4 blocks to buy represent 42.8% of the possible unicast addresses that are advertised in the global routing table. If the range is restricted to the 6.5 million /24 address blocks in which active WWW clients’ addresses are observed with IPv4 blocks that may be dedicated to network infrastructure and services being excluded, it is evident that roughly 450 million addresses may have been unused. If a large subset of addresses were available, they could be reallocated for IPv6 transition mechanisms that will require IPv4 blocks, or they could be offered as a commodity whose supply might last years in an IPv4 blocks buying marketplace, based on past rates of growth in IPv4 blocks use.

5. IPv4 blocks buying markets are an operational reality, governed by the respective RIR policies. The metrics introduced in the study offer detailed insights on the spatio-temporal utilization of network blocks, potentially helping Regional Internet Registries (RIRs) to determine the current state of address utilization in their respective regions. This could also help RIRs to see if a transfer conforms to their stated policy and to identify likely candidate sellers and buyers of IPv4 blocks. • The internet community is in the midst of a complex and costly resource-limited predicament, one that was foreseen but unavoidable. Operators continue to struggle with the question of whether and when to implement incremental changes to IPv4, to adopt IPv6, or to follow both paths. This study sheds light on the current state of the IPv4 blocks space to foster discussions and inform decisions on how to efficiently administer, manage, and govern the internet address space.

6. The process involved in buying IPv4 blocks take time. Fortunately, IPv4Hosting.com is the largest IPv4 broker with the most extensive inventory of IPv4 blocks available. Nonetheless, it still took some time to put together a suitable transaction and then took more time for the network administrator to integrate the new space in to his network.
