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 analyse 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 FTP sites listed below. Each RIR site also mirrors the files of the other RIRs.
