Do you want to improve the performance of your internet connection and have faster browsing speeds? Then setting up a caching DNS server could be the solution for you! In this article, we will explain what a caching DNS server is and how to configure it on a MikroTik router. Additionally, we will discuss the benefits of using a caching DNS server and why it is a great idea to set up.

MikroTik Caching DNS Server Configuration

What is a caching DNS server?

A caching DNS server is a server that stores DNS query results for a certain period of time. When a client makes a DNS request, the caching DNS server searches its cache for the requested domain name. If the domain name is found in the cache, the caching DNS server returns the IP address associated with the domain name to the client. This process is much faster than querying an external DNS server every time a client makes a request, which can cause significant delays and slow down the internet connection.

Why should you set up a caching DNS server?

There are several reasons why you should consider setting up a caching DNS server:

  • Improved speed: As we mentioned earlier, a caching DNS server can significantly improve the speed of your internet connection. With faster DNS query response times, you can browse the internet more quickly and efficiently.
  • Reduced network traffic: With a caching DNS server, there is less network traffic because clients are not constantly querying external DNS servers for the same information. This can lead to reduced bandwidth usage and improved network performance.
  • Better security: By hosting your own caching DNS server, you can reduce the risk of vulnerabilities and attacks from external DNS servers. Additionally, you can set up your caching DNS server to filter out malicious DNS queries and protect your network from potential threats.

How to configure a caching DNS server on a MikroTik router

Now that you understand the benefits of setting up a caching DNS server, let's go over how to configure one on your MikroTik router.

Step 1: Set up DNS caching

The first step in configuring a caching DNS server on your MikroTik router is to enable DNS caching. To do this, follow these steps:

  1. Open the WinBox software and connect to your MikroTik router.
  2. Click on IP > DNS in the left-hand menu.
  3. Click on the Settings tab and select the Cache item.
  4. Enable the cache by checking the Enabled checkbox.
  5. Set the cache size to a value that suits your needs. A good starting point is 10,000 entries.
  6. Set the cache replacement policy to LRU (Least Recently Used).
  7. Click Apply and then OK to save the changes.

Step 2: Add DNS servers

The next step is to add DNS servers to your MikroTik router. These DNS servers will be used to resolve DNS queries that are not found in the cache. To add DNS servers, follow these steps:

  1. Click on IP > DNS in the left-hand menu.
  2. Click on the Settings tab and select the Servers item.
  3. Click on the + icon to add a new DNS server.
  4. Enter the IP address of the DNS server you want to use. You can add multiple DNS servers by clicking the + icon again and repeating this step.
  5. Click Apply and then OK to save the changes.

Step 3: Configure your DHCP server

If you are using the MikroTik router as your DHCP server, you need to enable the caching DNS server as the primary DNS server for your network. To do this, follow these steps:

  1. Click on IP > DHCP Server in the left-hand menu.
  2. Select the DHCP server you want to configure.
  3. Click on the Networks tab.
  4. Select the network you want to configure.
  5. Enter the IP address of your MikroTik router as the Gateway IP.
  6. Enter the IP address of your caching DNS server as the Primary DNS server.
  7. Enter the IP address of another DNS server as the Secondary DNS server.
  8. Click Apply and then OK to save the changes.

That's it! You have now successfully configured a caching DNS server on your MikroTik router.

Conclusion

Setting up a caching DNS server on your MikroTik router has several benefits, including improved speed, reduced network traffic, and better security. By following the steps outlined in this article, you can easily set up your own caching DNS server and begin enjoying these benefits today.
