My Bone is connected to the Internet in two ways: via the RJ45 connection (
eth0
) and
via the USB cable (
usb0
). The
inet addr
field shows that my Internet address is
137.112.41.36
for the RJ45 connector.
On my university campus, you must register your MAC address before any device will
work on the network. The
HWaddr
field gives the MAC address. For
eth0
, it's
c8:a0:30:b7:f9:6f
.
The IP address of your Bone can change. If it's been assigned by DHCP, it can change at
any time. The MAC address, however, never changes; it is assigned to your ethernet
device when it's manufactured.
