I want the **eth0** interface to have a static IP address beside the one eventually assigned by DHCP (i.e. I want an IP alias on eth0:0). This is useful when I wan connect to the host even in an unknown network. To achieve this when dhcpcd is running, it is necessary to create an **user defined hook script**. See this page for more details: **[[..: | I want the **eth0** interface to have a static IP address beside the one eventually assigned by DHCP (i.e. I want an IP alias on eth0:0).

+ | If you are interested in transferring large files across the network, beware that a **100 Mbit LAN** imposes a limit of **14.7 Mb per second**, so the **USB 2** interface is enough to sustain that. But if you are interested into **Gigabit Ethernet** performance offered by the **Raspberry Pi 4**, you definitely need to use the **USB 3.0** interface. | ||
