This document summarizes the status of internet number resources as of December 2017 according to reports from the five Regional Internet Registries (RIRs): AFRINIC, APNIC, ARIN, LACNIC, and RIPE NCC. It provides data on available IPv4 address space, IPv4 and IPv6 address space allocated to each RIR over time, autonomous system number assignments, and IPv6 adoption rates among network members in each region.
