To be able to use the Internet on your home PC or your home network when you are on the move, you must have a fixed Internet address. For this reason, there are numerous dynamic DNS services that make it easy to find the right Internet address.
What is dynamic DNA?
Whenever you connect to the Internet with your router, you will receive a message from your provider. IP address is assigned. The IP address is automatically sent along with an outgoing data packet as a sender identifier. This allows the server on the other side to know where the requested data packets are going. Data should be sent. In the case of private Internet access, the dial-in node of your provider assigns a different IP address to the PC or router for each connection. This is also the case if you maintain a connection for 24 hours. Your provider will automatically terminate the connection after 24 hours and assign a new IP address.
A permanent address for your home network
Many providers offer fixed IP addresses. A certain fee is charged for this. A free option is a dynamic DNS service. With this form you get a fixed address. This address is available to you in the form of a sub domain. Many routers can be configured so that they can tell the respective DNS service the new address depending on the Internet connection. However, it is also possible that the PC is set up by the network to take over this task. For this to happen, however, the device must be permanently switched on.
Advantages of a dynamic DNS
To set up a PC for a dynamic DNS, the homepage of the selected DNS service, a corresponding tool can be downloaded. This tool is installed on the PC. In this way, the IP address is transferred directly to the respective service in the event of a change. With the DNS service, you can access the home network at any time, even when you are on the road. Of course, you also have the possibility to access the documents stored on the home PC from the office. On the other hand, you can easily store photos that you took on vacation directly on the home network. Remote access to your own network is therefore very useful in many areas.
What does DNA mean?
DNS is the abbreviation for Dynamic Domain Name Service. With the help of a DNS service, you can be reached from the net with a fixed domain name even if the IP address of the router at home changes. Usually a router is connected to the Internet at home via a DSL connection. The biggest problem is that the router is not only disconnected automatically after 24 hours, but also breaks down frequently. This also causes the public IP address of your router to change. From the office you can never know under which IP address you can reach your router at any time. Only with a DNS service you can solve this problem. The router passes the current IP address to the DNS server after the connection is established. If the DNS server has recognized your IP address of the router, it can establish a connection via the subdomain you have set up. The service always forwards your requests directly to the current IP address so that you are always up to date.
