Dynamic DNS, also generally regarded as DDNS, is a process for regularly updating IP addresses. This DNS service may be helpful to many people. Why? Let’s look into it now.
What is the fundamental purpose of Dynamic DNS?
Dynamic DNS (DDNS) is a Domain Name System service that lets you assign a hostname to a device and associate it with its IP address. So far, it’s a simple A or AAAA record. The dynamic component stems from the fact that you can configure your router to report changes in this device’s IP address and send an update message to the DNS server where the link was established. The IP address of the hostname will be updated there. It is a method of automatically updating a device’s IP address and providing availability without human intervention. You can use Dynamic DNS to ensure that your service is available.
If you do not use this DNS service and wish to use a device to provide a service, you may encounter the following issue. Your Internet Service Provider (ISP) will eventually update your IP address using a dynamic method such as DHCP. As a result, you will receive a new IP address, and all clients need to reconnect. Unfortunately, if you are not close to the device, you may not be aware of the new IP address and may experience prolonged downtime.
Additionally, you can pay for a static IP address and use your device to deliver service without being concerned that the IP address will change. Specifically, there are two issues. First, the price was more than a Dynamic Domain Name System to start. Second, if your IP address is consistent, hackers may have little trouble finding your device. They’ll be aware of it and do everything they can to take advantage of it. An unfavorable situation, isn’t it?
Benefits of implementing it
Some advantages of DDNS include the ones listed below:
- Dynamic DNS is a low-cost option. There are paid and free DDNS service providers. Therefore, it is much less costly than buying static IP addresses for the hardware in your organization.
- Availability – Although the IP address changes, you can still access your system using a constant name in the URL or a VPN.
- Easy to configure. Once you sign up for this service, it will automatically download.
- Installation and maintenance of video surveillance (CCTV cameras) will require a reliable Internet connection. Due to Dynamic DNS, they will remain operational around the clock.
- Dynamic DNS is a top consideration if you’re a corporate owner working remotely with a VPN, need wireless access for devices, or are hosting a website or personal blog.
Finally, you are now familiar with the purpose and main benefits of Dynamic DNS. It only requires a few minutes to set up and is incredibly simple. Most of the time, a free Dynamic DNS provider will suffice your needs, but if you want higher uptime and quality assurance, use a paying provider.
