Neither one of those is automatic. Someone with root privileges needs to install a package like apticron to get that. I believe, but have not confirmed: if you install a base Debian stable system, no extra packages, it will not initiate any connection without user action. An interface configured to use DHCP would ask for a new one on lease expiration. -dsr-
