Subject: [opennic-discuss] Punycode TLDs not works on OpenNIC root servers
Date: Sun, 15 Mar 2026 11:10:44 +0000

Hello. I got message from one of users that all OpenNIC servers do not work
with ccTLDs, which must itself written with punycode.

For example: I trying to use Bulgarian zone бг. with TIER0 and TIER1 servers
and no one responds correctly.
