As internet privacy and security continue to gain prominence, users are increasingly searching for ways to protect their online activities. One significant aspect of this is the encryption of DNS queries, which is where DNS over TLS (DoT) comes into play. In this article, we will explore whether Windows 10 supports DNS over TLS, its significance, and how to implement it.
What is DNS over TLS?
DNS over TLS is a security protocol that encrypts DNS queries between a client and a DNS resolver. The traditional DNS (Domain Name System) communications happen in plaintext, making them susceptible to eavesdropping and manipulation. Here’s a deeper dive into the workings of DNS over TLS:
How Does DNS over TLS Work?
When a user types in a website address, that request typically goes through a DNS resolver. In a conventional setup, this communication occurs unencrypted, allowing third parties to view and potentially alter the queries.
With DNS over TLS, however, the communication is encrypted, resulting in several benefits:
- Increased Privacy: Only the user and the DNS resolver can see the queries being made.
- Integrity: Protection against man-in-the-middle attacks ensures that DNS responses have not been tampered with.
When a DNS request is sent over TLS, it travels securely through the network, making it difficult for anyone to intercept the data.
Is DNS over TLS Supported in Windows 10?
As of now, Windows 10 does not natively support DNS over TLS. Microsoft has confirmed that while the system has made strides in enhancing privacy and security for users, DNS over TLS has not yet been integrated as a built-in feature. However, there are workarounds and third-party applications that can facilitate the use of DNS over TLS protocols on Windows 10 systems.
The Importance of DNS Security
The significance of securing DNS traffic cannot be overstated. Most users remain unaware that their DNS queries can be seen by internet service providers (ISPs), cybersecurity threats, and other entities. By implementing DNS over TLS, users can ensure that they have:
- Peace of Mind: Knowing that their browsing activity is anonymous makes for a safer internet experience.
- Access to Secure DNS Services: Using DNS resolvers that support DoT increases security and privacy.
Alternatives for Implementing DNS over TLS on Windows 10
Even though Windows 10 does not support DNS over TLS natively, there are compelling alternatives. Below we will cover some methods that can be adopted to enable this enhanced security.

What is DNS over TLS?
DNS over TLS (DoT) is a protocol used to encrypt DNS queries and responses between a client’s device and DNS servers. This encryption helps protect against eavesdropping and man-in-the-middle attacks by ensuring that third parties cannot easily see which websites a user is trying to access. DoT operates over a secure transport layer, often making DNS requests more private and secure compared to traditional DNS.
By using DNS over TLS, users can enhance their online privacy and security. As DNS queries can reveal a lot about a user’s browsing behavior, the added encryption helps in safeguarding this information from potential attackers. This is especially vital on unsecured networks, like public Wi-Fi, where data can be more vulnerable to interception.
How do I enable DNS over TLS on Windows 10?
To enable DNS over TLS on Windows 10, you need to adjust your network settings. Start by going to the Control Panel and navigating to Network and Internet settings. From there, access the Ethernet or Wi-Fi connection you are using, then choose the “Properties” option. Here, you’ll find the Internet Protocol Version 4 (TCP/IPv4) and Internet Protocol Version 6 (TCP/IPv6) settings that need to be configured.
You can then change the DNS server addresses to that of a DNS provider known to support DNS over TLS, such as Cloudflare or Google. Once configured, you may also need to use a third-party DNS client that supports DoT, as Windows 10 does not natively support this protocol out of the box. After setting everything up and restarting your device, you should benefit from the added security of DNS over TLS.
Will using DNS over TLS speed up my browsing experience?
While DNS over TLS offers enhanced security, it does not necessarily guarantee an increase in browsing speed. The performance can vary depending on the DNS provider you choose to use. Some providers may have faster response times than others, and your experience will likely depend on their server proximity and load. In many cases, users may find that their browsing speed remains the same or is slightly slower due to the overhead of encryption.
However, if you switch from a less reliable DNS provider to one that supports DNS over TLS and has a reputation for speed, it could result in a better overall experience. Ultimately, the performance of DNS over TLS will be influenced by both the DNS resolver you choose and your internet connection quality.
Are there any risks associated with using DNS over TLS?
While DNS over TLS provides a higher level of security and privacy, it is not without its risks. One concern is that the encryption can potentially complicate troubleshooting DNS issues, as standard DNS troubleshooting techniques may not be as effective. Additionally, if you misconfigure DNS settings or choose a DNS provider with reliability issues, it may lead to connectivity problems.
Another risk is related to the trust factor of the DNS provider you choose. While DoT encrypts your queries during transmission, the DNS provider can still see your queries. If the provider does not uphold strict privacy standards or logs your data, it could undermine the privacy benefits DNS over TLS is supposed to offer. It’s crucial to choose a reputable DNS provider that prioritizes user privacy.
Which DNS providers support DNS over TLS?
Several DNS providers offer support for DNS over TLS, including well-known names like Cloudflare, Google Public DNS, and Quad9.
