I am a parent of an Argentinean citizen. Its a permanent and comes in plastic. Yes, migraciones already got an email, will share their answer with you guys, and the embassy told me that I will need to do in person in Argentina. Which is actually hard to believe for me. As for Argentines abroad, you can register with your local embassy and ask for a "cambio de domicilio" and receive a new DNI with the correct address.
