Q6810010: When performing a DNS check with type 'ANY', no DNS records exist. But if I specify type 'A', DNS records do exist. Why is it?
With most DNS servers, using a DSN query with the 'ANY' type should return all known DNS records for the specified host. However, with some DNS server, the servers only return a 'CNAME' record. ActiveXperts Network Monitor reports that no DNS records exist. With these DNS servers, you should specifying 'A', 'AAAA', 'NS', 'MX' or other explicitely. One example of DNS servers suffering from this problem is the public Google DNS server (8.8.8.8).
