Ah, md is an obsolete RRTYPE. Nevermind! (Just like typing dig a.)

The dot. Use dig md. so dig doesn't take the md as the obsoleted
RR type md for mail destination.

There are more of those name clashes such as MX, CH  etc.

 Indeed. But why does it query for NS?

When you don't specify a name, dig looks up ./NS by default. 

When the code for this was originally written, I guess it didn't
occur to anyone that you might have specified a type but not a name.
