Yeah sorry, I should have said that I was only looking into the time 
frame 2017 till now.

frequently.

I think I aggree that it is unlikely to change frequently, however, 
there is not a single snapshot in archive.org for 2018.

Best regards,
Lars

Well it certainly true that time elapses between each crawl, so it's possible that some changes could be missed, my understanding is that the Internet the scroll frequently enough that changes would be detected at least every month or so.

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?
