What's keeping xn--jvro20bz3knw1a.tokyo from an A

  1. Nameservers without IPv6
    ns2.value-domain.com, ns1.value-domain.com all have no AAAA record, so a resolver that only speaks IPv6 can't look your domain up. Most DNS providers offer IPv6 nameservers; ask yours, or move DNS to one that does.
