Weird questions from police officers

Hello,

Im a foreigner and i had a many police traffic controls already. Is it normal when police officer still asking me where do I live?

Last time i got this question from royal military police near to schiphol and one of them wrote my adress to his phone into “notes”.

Do I have to answer these questions?

I don't have a problem with the police, but it doesn't seem right to me that they should write down to their phone where I live, especially when I haven't done anything.

Thank you
