</ref> which lack a user interface, can use so-called ''ARP stuffing'' to make an initial network connection, although this is a misnomer, as ARP is not involved.

ARP stuffing is accomplished as follows:
# The user's computer has an IP address ''stuffed'' manually into its address table (normally with the ''arp'' command with the MAC address taken from a label on the device)
# The computer sends special packets to the device, typically a [[Ping (networking utility)|ping]] packet with a non-default size.
# The device then adopts this IP address
# The user then communicates with it by [[telnet]] or [[http|web]] protocols to complete the configuration.

Such devices typically have a method to disable this process once the device is operating normally, as the capability can make it vulnerable to attack.
