Hi Mel, I already checked Archive.org - it holds two previous copies.
lets you download each version of the list that archive.org noticed changed
According to Archive.org's own Note this seems to be inaccurate: This calendar view maps the number of times https://www.cidr-report.org/bogons/freespace-dec.txt was crawled by the Wayback Machine, not how many times the site was actually updated. , or am I missing something?

Lars,
Archive.org has snapshots going back several year. Just feed in the URL you posted, ad you’ll get a history that lets you download each version of the list that archive.org noticed changed. In my experience, that is pretty comprehensive.

Hi everyone,
In order to sanitize historical BGP data I would like to use historical Bogon lists. The CIDR report generates those lists on a daily basis (e.g. https://www.cidr-report.org/bogons/freespace-dec.txt for prefixes) but, as far as I know, it does not keep a history of those files - it only holds the most up-to-date file. Does anybody know of a repository that contains such bogon lists for historical data, or, did anybody continiously fecthed and saved CIDR report's bogon lists?
Best regards,
Lars
