Today, we’re introducing Dynamic Response, a new traffic balancing setting mechanism that gives our customers users granular control over DNS record answers. Dynamic Response is a new feature of Gcore Managed DNS, an extension of our GeoDNS feature range. GeoDNS is a form of load balancing that helps you optimize traffic allocation between different, geographically distributed servers, ensuring lower latency and better resiliency.
Dynamic Response allows you to manage applied metadata values in an intuitive way within the Gcore Customer Portal or via API. Dynamic Response leverages “pickers” to assemble the proper order in which our system will assess the incoming query. You can easily change the order by dragging selected pickers. By setting up different metadata in a record set, you can easily configure different DNS answers based on query parameters from the same DNS record.
Benefits of Dynamic Response
GeoDNS allows you to deliver regionalization and ensure the availability of your digital services globally, so your end users get a geographically tailored experience with fast response. With Dynamic Response, configuring your DNS record sets is more convenient and accurate than ever before. You can easily set up your desired configuration for even the most unique and sophisticated network requirements.
How It Works
The logic of this order operates from top to bottom: the system validates query parameters with the first condition. If no match is found, it proceeds to the second condition, and so on.
Consider a user request from the 109.105.148.0/24 subnet. According to our GeoIP database, their IP address is registered in Luxembourg.
Let’s compare how the system validates two sequences using the data in Figure 2, and what responses the user will receive in each case:
- IP > Country > Continent
- Continent > Country > IP
| Sequence #1 | Sequence #2 | |
| Condition 1 | IP: match | Continent: miss |
| Condition 2 | Country: skipped | Country: match |
| Condition 3 | Continent: skipped | IP: skipped |
| DNS response | 10.0.0.2 | 10.0.0.0 |
Changing the order of conditions in the sequence can affect the final result, even if the initial metadata values of the DNS records remain unchanged.
Presets for Easier Configuration
To enhance ease and convenience, we’ve added presets for the most common use cases in load-balancing settings: Geo DNS, Geo Distance, and Weighted Shuffle. These presets allow users to quickly and efficiently apply the most appropriate settings for their specific needs.
For a more detailed explanation of these presets and how to use them, please refer to Dynamic Response product documentation.
