If I tell you 5% of all DNS nameservers have zone transfers enabled. Is it too much?
Well... actually our experiment showed 8% of all authoritative nameservers allow zone transfers 🤷♂️

I did it for several countries so you don't have to
I will leave an interpretation to the reader
1st chart -> number of AS per capita
2nd chart -> average number of IPs (v4) per capita
Honestly, Japan quite surprised me

Quiz time: can you think of a single legit reason to put RSA private keys to DNS TXT records? Sounds like a nonsense but people really do that
We did a small research on this topic some time ago
