What's keeping beltev.online from an A

Mail servers without IPv6
mx2.hosting.reg.ru, mx1.hosting.reg.ru have no AAAA record, so mail from IPv6-only servers can't reach them directly. If a provider runs your mail, that's their setting; if you run it, add AAAA records for these hosts.
Nameservers without IPv6
ns1.hosting.reg.ru, ns2.hosting.reg.ru 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.
