Dynamic dns ( dyndns ) and Vpn (Virtual private network) :

To access some computer localised in other agency, you must have a phisical private connexion. But this solution is impossible due to the high cost.

But if you use a dynamic dns service and a dyndns client installed on the machine you would like to access, you will able to communicate with this machine (reading data or other).

The vpn network is a vitual network which is made between all local networks of agencies.

And dynamic dns service ( dyndns service ) is a good way to know the internet address ( ip ) and set

subdomains name to each local desktop that is able to be joined by an other machine in the virtual network.

Each machine has a dyndns clinet ( a dyndns agent ) that communicate with the dyndns server to set the whole dns domain config.

The dynamic dns processing is a best way to set a virtual private network ( VPN).
