Dynamic DNS
ETERNITY NE supports Dynamic DNS Server client of the Service Provider Dynamic DNS.org. Dynamic DNS
(DDNS) is a service that maps internet domain names to IP addresses. Dynamic DNS may be required if you have
registered SIP extensions with the Registrar Server of ETERNITY NE.
When you register IP extensions with ETERNITY NE and your network uses dynamic IP addressing (DHCP or
PPPoE) to assign the WAN IP Address
70
, all the SIP clients registered with ETERNITY will need to be updated with
the new WAN IP Address to be able to function. Dynamic DNS resolves this mapping a host name (domain name)
(host name) and the preferred WAN IP Address. Each time a new WAN IP Address is assigned by the network,
ETERNITY updates the mapping on Dynamic DNS server.
You may register with DynamicDNS.org server to use this service. If you have registered with Dynamic DNS.org,
do the following:
1. Select the check box Enable Dynamic DNS. Default: disabled.
The DynamicDNS server stores the mapping between hostname and IP Address, which can be updated
periodically. However, if the ETERNITY frequently sends IP Address update requests to the DDNS server,
the server is likely to block the hostname in its database and terminate the DDNS services provided to
ETERNITY.
So, if you restart the ETERNITY frequently, chances are that DDNS server may block the hostname of
your system. This will in turn affect the ability of the system to receive the calls using DDNS hostname
since the entry (mapping between hostname and IP Address) in the DNS server will be deleted in such
scenarios.
ETERNITY NE updates the WAN IP Address in the DDNS server at each Power ON. You can also update
the WAN IP Address at any time you want, as required.
2. Enter the User ID you created on DynDNS.org in the field User ID. A maximum of 40 characters, including
all ASCII characters are allowed.
70. According to your installation scenario and Preferred WAN you configured.
