dnslookup 'пример.рф' 8.8.8.8

2025/05/15 15:36:44 [fatal] Cannot make the DNS request: bad question section: mismatched name "\\208\\191\\209\\128\\208\\184\\208\\188\\208\\181\\209\\128.\\209\\128\\209\\132."

Looks like dnslookup is sending IDNA queries as-is, without encoding them into Punycode. This makes testing IDNA support in DNS harder, as one basically has to encode the IDNA into Punycode themselves.
