My definition of "domain name space" is the name space of all existing domain names, so there is a significant difference there. These terms are not rigorously defined for the most part, so are sadly subject to interpretation. A query for a domain name that elicits NXDOMAIN means that the domain name did not exist in the relevant domain name space. But the queried name nevertheless still was a domain name. Shumon.
