RPKIViews 2021 Amalgamation - https://doi.org/10.5281/zenodo.18082494

The RPKI is an infrastructure which helps secure the global Internet routing
system. RPKIViews.org is a global multi-perspective data collection initiative.
This dataset is an amalgamation of 46,507,392 signed RPKI objects extracted
from 26,273 RPKIViews.org snapshot archives discovered between December 6th,
2020 and December 31st, 2021 inclusive. The objects originally were fetched
from publication servers which were discovered using the Trust Anchor Locators
of the following Regional Internet Registries: AfriNIC, APNIC, ARIN, LACNIC,
and RIPE NCC. 

The median RPKI object size in this dataset is 1,908 bytes and the total
cumulative size of all objects in uncompressed form is 78,1 gigabytes.

Not all objects contained within this dataset comply with the requirements of
modern day RPKI relying party implementations.

The following file naming scheme is used for the tar archive members: every
filename is the URL-safe Base64-encoded SHA-256 message digest of the object's
ASN.1 encoded content. For performance reasons, the directory hierarchy is
constructed using the last few bytes of the filename. The file's recorded
last-modification timestamp is constructed following the procedure outlined in
RFC 9589. The tar achive adheres to the IEEE Std 100.2 POSIX.2 "USTAR"
interchange format and is compressed in Zstandard (RFC 8878) form.
