Ah, yes, thanks. But the numbers are disconcerting. I see twice as
much queries per connection with IPv4 than IPv6, but only for DoT. For
DoH, it is the opposite. This may be simply because it is a small
resolver so the numbers are not statistically significant.

Which is the case, no?

newServer({address="[::1]:853", name="Local-Unbound", tls="openssl", subjectName="dot-backend.bortzmeyer.fr", validateCertificates=true, useClientSubnet=false, maxInFlight=1024})
