Hm, do you know where the big jump is coming from (way more adds than removals). Interestingly for v30 the change was basicially the opposite. Am I missing something or is this weird?

The v30 update ended up removing all of the cjdns nodes and a ton of i2p and onion nodes as my crawler had a bug that caused it to not be able to reach those nodes. Since that was fixed, this update includes all of those nodes back. Notice how nodes_main.txt now has 2059 nodes while in v30 it was only 849.

I re-ran the steps in docs and compared my produced files against the files added here. I didn't see any suspicious differences.
Here is some of the output of my vibe-coded diff scripts ("old" means the file added here, "new" is mine):

Would it be interesting to add a much cleaner and less verbose version of a diff script to the repo here? We have quite a bit of similar functionality in kartograf but it's working the other way around: it analyses the asmap file under lens of some ip list, while this is basically working the other way around, so it doesn't apply. But this might be interesting to easy review burden.
