Dynamic DNS is necessary when the IP address of a server tied to a domain name constantly changes. This is typical when the server connects to the Internet using a modem. In Dynamic DNS, the server contacts the DNS provider each time its IP address changes in order to update the DNS entry for the domain hosted by the server.

Dynamic DNS is simply a way of attaching a static hostname to a dynamic IP address. On the Internet, there are a limited number of IP addresses. When you connect to your ISP, you are assigned a temporary IP address that other computers use to find you while you are connected. Once you disconnect, that IP address is given to someone else, and so on.

Yes. PlanetRemote is compatible with all dynamic DNS software. You will need to install PlanetRemote Standard Edition only on the computer you want to control remotely. You will be able to take control of your computer over the Internet or LAN with the name you have already assigned to your computer.

You need to change the 'Name Server' addresses that are listed for your domain name. You typically go to the website where you bought your domain name, ie: BulkRegister, Network Solutions, Register.com, etc and change them there. You have to specify at least 2 different 'Name Servers' for your domain - you can use ns1.changeip.com @ 66.185.162.20 and ns2.changeip.com @ 68.15.30.144. Wait anywhere from 12-48 hours usually for the registry to replicate your new 'Name Server' selections.

This depends on your requirements. If you would like to have your DNS records automatically updated each time your IP changes then you will need client software to automatically tell us that you've moved. This software has already been written for just about every platform out there. If you want to semi-automatically update your records you can use the 'Update Set x Now!' function from the web site menu once you are logged in.

Feel free to contact me, I will contact the service team and see with them how to support their service in DU.

Yes. We allow you to update your IP address as it may change from time to time using a simple one line URL request. Documentation for supported clients and the update protocoll specification can be found here.

Yes. For instructions on how to enable dynamic DNS updates for your domains and links to supported client software, see our Dynamic DNS tutorial.

Yes. When the main window is open, click the button with a check mark. It will open the properties window. From there, click network. You can now enter a proxy, but don't forget to click ok!!

What should I do if the old Proxy server is still set up (or I have another proxy server set up by my ISP or company?)

You may consider VNC by AT&T Labs Research. On your home computer you install the server-side components. From the client side you use the dynamic DNS of your computer at home to connect and that's it. If you have Windows XP Professional at home, you may also consider the Remote Desktop Connection. I did not try it over the Internet but it must work the same way.

You must, of course, own a DNS server permanently connected to the Internet. Then you will need to write or to adapt some scripts to process the update requests and to manage both the user and the record databases. You can find information about this in the Open Source domain (e.g. the GnuDIP server). You may also take a look at DynoDns.net or ProutDNS which both released the source code of their scripts.
