It is *not* a bug in any name server implementation. It is a 
misconfiguration in .BY's setup. On 30th March, I already pointed to a 
link from the dns-operations list which contains a detailed explanation:

https://lists.dns-oarc.net/pipermail/dns-operations/2022-January/021501.html

Please read that message fully to understand the problem. It's pointless 
repeating it here.
