Use the command AT#DHCP to automatically activate or deactivate the

dress from a DHCP server when switched on.

The settings from the stored profile (AT#IP, AT#NM, AT#GW) are not affected
by the usage of DHCP. For AT#DHCP=0, the old values will again be available.

its settings from the DHCP server.
