Dynamic DNS is a system which allows the domain name data held in a nameserver to be updated in
real time. The most common use for this is in allowing an Internet domain name to be assigned to
a computer with a varying (dynamic) IP address.
This makes it possible for other sites on the Internet to establish connections to the machine
without needing to track the IP address themselves. A common use is for running server
software on a computer that has a dynamic IP address, as is the case with many consumer
Internet service providers.
To use Dynamic DNS records with Joker.com, you have to create at least one Dynamic DNS record.
Additionally, the Dynamic DNS feature has to be activated.
After this, you have to configure your (DSL-) router or your Dynamic DNS
software on your computer.
Currently, there is a limit of 20 records per domain. The nameserver records have a TTL (time to live - defines the latency before changes become visible) of 60 seconds.
Please note: The "username" and "password" referred to in this section are not identical with your standard Joker.com credentials. Instead, you will be provided with special credentials when you create your DynDNS entry, which are only valid for those entries.
A hardware device like a DSL router often is able to handle Dynamic DNS itself. As an example, this is the corresponding section of a Fritz!Box DSL router:
In the menu (web ui), you have to chose "Preferences" => "Internet" => "Dynamic DNS".
You have to enable "Dynamic DNS" with the checkbox. Then choose "Custom" as Dynamic DNS Provider.
The input fields then have to be filled like this:
Domain name: <enter your Joker.com Dynamic DNS record (Domain name) here>
Username: <enter the username you got at Joker.com's DNS management for this domain>
Password: <enter the password you got at Joker.com's DNS management for this domain>
Note: SSL is also supported, though not all devices might support this: https://svc.joker.com/nic/update?...
Domain name: www.yourdomain.com
A popular free Dynamic DNS Windows updater is "DynDNS Updater" from Kana Solution.
Please download the latest stable version from their site , and install it. If you use the version with setup program, or start the DynDNS.exe for the first time, you will be presented a "configuration wizard".
When it asks for "My Group", enter "Joker". For "Username" and "Password", please use the credentials (see above) you got in Joker.com's service zone.
Then please chose "enter manually" when asked for "automatic download". The next dialog allows you to add the hostname or domain you whish to use as Dynamic DNS record, as configured at Joker.com, like "www.yourdomain.com".
Finish the rest of the wizard, and leave the program (exit)! Please locate the file "DynDNS.ini" - usually it is in c:\program files\DynDNS Updater (or in the directory you used to extract the package without installer).
Open it in an editor (Notepad is fine), and search for the section [Options]. Please add the line
and save the file.
Then download the text file "joker.profile" attached below, and store it somewhere - e.g. in the DynDNS Updater directory. This text file is the profile to be used for the Joker Dynamic DNS service.
Restart DynDNS Updater, and chose "Settings" (right mouse click on task bar icon).
Select "My Group 'Joker'", click "edit", chose tab "Options", type "joker.com" in inputfield "Provider", and click on the browse button below this. Navigate to the text file you downloaded before, and select it.
Leave by pressing "Ok" - and you are done. DynDNS Updater should work now.
