How to Troubleshoot Smart DNS Issues?

Have you already set up smart DNS on your device, but something doesn’t seem to be working properly? If you’ve successfully set up smart DNS on your device but still can’t get your favorite streaming service to operate, try the following:

  1. Try both smart DNS servers subtly.
  2. You received two server addresses after activating the smart DNS service. If your device has a DNS box that can only handle one DNS address, try the first one!
  3. If your device has two DNS boxes for two DNS servers, consider using the same DNS server on both lines, as shown below:
  4. Uninstall and reinstall the streaming app, or at the very least clear the program’s cache.
  5. Restart your computer.
  6. Set custom DNS on your router by logging in.
  7. As a primary DNS, use, and as a secondary DNS, use Because there are so many routers, each with its interface, you may wish to consult the user manual for your router or hunt for instructions online.
  8. After you set up smart DNS, keep in mind that you can only use smart DNS for one IP address at a time. However, you will lose your internet connection if you set up smart DNS for a different device. (Smart TV, Xbox).

Does your network’s IP address change independently?

In this case, you do the following:

  1. Visit OysterVPN from a computer or a mobile device.
  2. Make sure your laptop or phone is on the same.
  3. Go to the smart DNS page after logging into your OysterVPN account.
  4. Change your IP address by clicking the Change IP button.
  5. It will enable smart DNS for your new IP address.

It’s time to cross-check if smart DNS works on your TV or gaming console! Unfortunately, smart DNS is only available for IPv4 addresses. Some networks, however, support both IPv4 and IPv6 protocols. So, if you’re getting this issue, it means your device is also using IPv6.

Follow the below steps:

  • Disable IPv6 on the device you’re using to access our website’s smart DNS service.
  • Turn off IPv6 on your router.
  • Make contact with your Internet Service Provider (ISP)

You may have observed that the IP address displayed on your TV differs from the one used for smart DNS. Your TV will only display the internal (private) IP address because you enabled smart DNS for your exterior (public) IP address; your TV will only display the internal (private) IP address.

Internal IP addresses are normally in the format 192.168.x.x and are commonly used for internal communication between devices on the same network. It is not visible to the public and has no bearing on the use of smart DNS, so you can disregard it and continue with the smart DNS configuration.
