Ethernet Connection

The IT Manager may also create a host name for the receiver.
The choice of using or not using the DHCP mode within the
local network, and the consequence of this choice on which
information to provide to the remote system for the
connection are also the decision and responsibility of the IT
Manager. When DHCP is used, an account may be opened on
DynDNS.com to track the dynamic IP address assigned by the
ISP to the receiver’s public access point. See Creating an
Account on Dyn.com on page 91
