What's keeping mulhacen.cat from an A

  1. Nameservers without IPv6
    ns1.cdmon.net, ns2.cdmon.net, ns3.cdmon.net, ns4.cdmondns-01.org, ns5.cdmondns-01.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.
