Hi there,
Jonathan Hoppe already reported this and it's fixed in the upcoming
release, I forgot to send
patches your way as well, my bad. So here they are, both for QNAME
case insensitivity
and name compression.
Best,
Marek

I exposed Knot 1.4.0-rc2 to real queries, and noticed
it was giving
REFUSED responses for a significant number of queries. Digging further,
it looks like the QNAMEs were mixed-case, such as:
42.234.11.86.In-adDR.ArPA
So here's where I discovered a show-stopper bug:
