Try http://dnscheck.pingdom.com/?domain=www.empleosmadrid.es or http://www.intodns.com/empleosmadrid.es instead.
The error you were given means that the nameservers for empleosmadrid.es
have not delegated the subdomain of www.empleosmadrid.es
to a different set of nameservers.
The confusion I think you are having here is that the check you are performing is for a zone and not for a record. The www.empleosmadrid.es
record is working fine. The empleosmadrid.es
zone is working fine. The www.empleosmadrid.es
zone doesn't exist, so you get an error message.
Of course, let me know if you are actually trying to delegate the www
subdomain to a different set of nameservers, because if you are then you have a different problem.
If all you want to do is check that a record exists and returns the correct value, a simple dig www.empleosmadrid.es
or nslookup www.empleosmadrid.es
is enough for that. The IntoDNS check above includes a lookup for www
.
