Dynamic DNS
Configuration – Network > Dynamic DNS
The Dynamic DNS client (DynDNS) is used to update DNS hostnames with the current IP
address of a particular interface. It operates in accordance with the specification supplied by
dyndns.com (go to http://www.dyndns.com/developers/specs/). When the interface
specified by the interface and interface instance number parameters connects, the client
checks the current IP address of that interface and if it differs from that obtained from the
previous connection,
www.dyndns.com is contacted and the hostnames specified in the
Hostname parameters are updated with the new address.
Service Provider
This parameter is used to specify the Dynamic DNS service that will be updated with the
router’s IP address. Although the protocol is standard, there are subtle differences in the
implementation. Choose Dynamic DNS for services provided by dyn.com. Choose No-IP for
services provided by noip.com. Choose Other for any other service using the Dynamic DNS
standard.
Service Provider Hostname
When selecting ‘Other’ as the service provider, this text field should be used to specify
the provider name. This text will be added to the HTTP update string sent to the remote
server. The service provider hostname should be obtained by contacting the service
provider’s own technical support.
Host and Domain Name(s)
These five text boxes specify up to five host/domain names that are to be updated using the
service.
Destination port #
The value in this text box specifies the IP port to use as the destination port. The default
value is 0 which causes the router to use the default port number which is port 80.
DynDNS User Name
The value in this text box specifies the username to use when updating the hostnames. This
will have been supplied by the service provider.
DynDNS Password
The value in this text box specifies the password to use when updating the hostnames. This
will have been supplied by the service provider.
Confirm DynDNS Password
Enter the password into this text box to confirm it.
