7.2. HOW TO CONFIGURE DYNAMIC DNS
Note that the IP 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.
7.2 How to con
fi
gure Dynamic DNS
Dynamic DNS allows remote contact with the AsteRx-U MARINE Fg using a hostname.
When devices are connected to the internet, they are assigned an IP address by an internet
service provider (ISP). If the IP 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 IP address is currently
assigned to it.
To make use of this feature on the AsteRx-U MARINE Fg, 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. In the example shown in Figure 7-3, the hostname
asterxu.mine.nu
has been
registered with dyndns.org. The
Bind
option, selected in this case, tells the Dynamic DNS
provider only to update IP addresses assigned over an Ethernet LAN connection.
