Here's a link for D&G.
Looks like Futura. Not sure what exact version, though.

Very close to Futura but there are some differences: the G and B for example, and in the weight of Futura that best matches the logo, which is Futura regular (not book, heavy, etc) the points of the N and the A would still be sharp. I dunno... so it could be customized or a Futura knockoff.

Did you look at Avant Guard? Maybe a medium weight

That is definitely not Avant Garde. Look at the 'G'.

Nah, it's a version of Futura. Can't explain the cut-off
bits on the A and N, but all the other earmarks point
to Futura. Customized? Could be.
