Configuring system dns when listen_addresses = ['0.0.0.0:53']

[ghost]

EDIT : pointless, resolved, my misunderstanding the basics.

Hi,

Running dnscrypt-proxy 2.1.5 / Windows 7
No issue, simple naive question.

Up to now I've always set listen_addresses = ['127.0.0.1:53'] and, accordingly, system dns to 127.0.0.1
If I wish to listen to all IPv4 addresses, I should set listen_addresses = ['0.0.0.0:53']
Question is : should I set system dns accordingly to 0.0.0.0 (instead of 127.0.0.1)?

I've set listen_addresses = ['0.0.0.0:53'] and system dns to 127.0.0.1 : no issues but I don't know if ALL IPv4 addresses are handled.

Thanks!
