8.5 How to configure Dynamic DNS
Dynamic DNS allows remote contact with the AsteRx SB Sx 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.
Step 1: Open a Dynamic DNS account
To make use of this feature on the AsteRx SB Sx , you should
fi
rst create an account with a
Dynamic DNS provider to register a hostname for your receiver. The AsteRx SB Sx supports
the following two services:
•
Dyn DNS: http://dyn.com/
•
No
I
P: http://www.noip.com/
Having opened account, you can then create a host service for which you will need to specify
a URL or hostname for the receiver (e.g. axsb.ddns.net).
Step 2: Configure the Dynamic DNS settings of the receiver
I
n the
Dynamic DNS
window of the
Communication
menu, the hostname of the receiver
and other Dynamic DNS settings can be entered.
I
n the example shown in Figure 8-10, the hostname
axsb.ddns.net
has been registered
with ddns.net. The
Bind
option tells the Dynamic DNS provider to automatically update
I
P
addresses assigned over either an Ethernet or WiFi connection.
