 With a Device Tree, the kernel will automatically search for and load modules that support the indicated enabled devices. As a result, by creating an appropriate DT overlay for a device you save users of the device from having to edit `/etc/modules`; all of the configuration goes in `config.txt`, and in the case of a HAT, even that step is unnecessary. Note, however, that layered modules such as `i2c-dev` still need to be loaded explicitly.

 The Raspberry Pi uses `dhcpcd` to configure TCP/IP across all of its network interfaces.

This includes assigning each interface an IP address, setting netmasks, and configuring DNS resolution via the Name Service Switch (NSS) facility.

 Note that if you have several Raspberry Pis connected to the same network, you may find it easier instead to set address reservations on your DHCP server. In this way, each Pi will keep the same IP address, but they will all be managed in one place, making reconfiguring your network in the future more straightforward.
