So what you're saying is that OpenBSD doesn't reject invalid DNS names?

Itβs not about OpenBSD, other non-Linux systems (& musl) are fine with it as well. The name is invalid, but glibc has a unique behavior.

Just like you can ban resolver implementations by leveraging their hardcoded limits on the number of indirections in compressed names.

So actually you're banning glibc not Linux?
