My guess is that you are asking recursive resolvers, these may
or may not have the SOA record cached, which is where the
information you refer to is stored.

When you do an "any" query it returns cached data if it exists
or retries the query. So my guess is that the queries that
"worked" were for zones that weren't cached.

If you want to know these values you should query one of the
servers for the domain in question, or request the SOA


dig @NS1.US.dell.com. dell.com any    
dig dell.com soa
