In todays connected world, many people would like to be able to access their computer, DVR, webcam or camera system remotely without having to remember a confusing (and ever changing) IP address? DynDNS is a great option for those who need Dynamic DNS and Remote Access capabilities without any bells, whistles or fireworks.
What Does It Do?
DynDNS Pro allows you to assign an easy to remember hostname (such as yourname.dyndns.org) to your location’s IP address. By installing an update client on a device at that location, your hostname is automatically updated whenever the IP address changes, ensuring you can access your device remotely at any time.
Most internet service providers charge you extra to provide a fixed IP address that does not change. Others don’t make that an option at all. DynDNS allows you to get around those restrictions and still get access to devices in your home or business. This service works in conjunction with a good router or firewall in your location. THink of the router as the locking system for your internet. And DynDNS as map of how to get to your front door.
After signing up and paying a low one year subscription rate of $25, you download a small client piece of software that you run on your Mac or Windows machine. The software needs to run on a machine that will be left on all the time. This software senses your external IP address provided by your internet service provider and sends it to the DynDNS service. On the service you setup a permanent url with DynDNS as the access point for your network. An example might be http://myhouse.dyndns.org. The software you have installed on your computer checks for the actual IP address you are using from your service provider every 5 minutes. Lets say for example it is 100.120.130.140. It then tells the DynDNS service that the url ttp://myhouse.dyndns.org is at the ip address 100.120.130.140.
To access the devices in your location, you simply configure them for http://myhouse.dyndns.org rather than the ip address numbers. DynDNS does the network address translation to rout any requested traffic to your location front door. Once at the door, port forwarding on your router needs to be configured to provide the necessary secure access. This process may sound difficult but a networking professional could assist you in setting it up.
With a service like DynDNS you can get access to those security cameras, network storage devices, or DVRs easily from anywhere in the worls. When you service provider will not give you a fixed IP address for a reasonable cost, DynDNS can come to your rescue and make your connections work.
