8.2. HOW TO CONF I GURE DYNAM I C DNS
After reboot, the Ethernet Status fi eld should now show the correct I P settings as shown in
Figure 8-2.

Note that the I P settings will keep their value after a power cycle and even after a reset to
factory default in order to avoid accidentally losing an Ethernet connection to the receiver.
8.2 How to configure Dynamic DNS
Dynamic DNS allows remote contact with the PolaRx5S using a hostname.
When devices are connected to the internet, they are assigned an I P address by an internet
service provider ( I SP). I f the I P address is dynamic then it may change over time resulting in a
loss of connection. Dynamic DNS (DynDNS or DDNS) is a service that addresses this problem
by linking a user-de
fi ned hostname for the device to whichever I P address is currently
assigned to it.
To make use of this feature on the PolaRx5S, you should fi rst create an account with a
Dynamic DNS provider ( dyndns.org or no-ip.org ) to register a hostname for your receiver.
I n the example shown in Figure 8-3, the hostname polarx5.mine.nu has been registered with
dyndns.org. The Bind option, selected in this case, tells the Dynamic DNS provider only to
update I P addresses assigned over an Ethernet LAN connection.
