On 5 January 2004, the Regional Internet Registries (APNIC, ARIN, LACNIC, and RIPE NCC) implemented a new standard file format for reporting the current state of Internet resource allocations and assignments for: - IPv4 address ranges - IPv6 address ranges - AS numbers The new file format, now available from all RIRs, ensures consistency and makes it easier for users to integrate and analyze data from different sources. The reports contain a snapshot of the status of Internet number resources, without any details of transaction histories. They are produced daily and include: - Information summaries - GPG key signatures - MD5 checksums for verification Statistics files ---------------- The latest statistics files are available from the RIR sites listed below. Each RIR site also mirrors the files of the other RIRs.
