Try asking the correct type (A record only) and you'll have the correct
answer : the three PDNS servers having delegation for mirror.centos.org
will only answer for A records (we have obviously no MX record for
mirror.centos.org and, unfortunately, no AAAA records for those machines
either)
PS : host is considered "deprecated" so switch to dig instead ? ;-)
