Is Encrypted DNS Slower? Explained!

Encrypted DNS protocols are a good idea if you are concerned about the security of your communications. The downside is that they can slow down connection speeds, but you may not know this until you’ve used them. DoT and DoH are modern variations on SSL that do the same job, though they have different strengths. For example, DoT has a lower median response time than DNS and is faster in latency.

However, encrypting DNS can have other negative effects on your network. The biggest problem with DoH is that it can negatively affect the security of your connection. While it’s true that DoH is a faster protocol, it doesn’t mean that encrypted DNS is the best choice. Some users prefer using encrypted DNS because it offers more privacy and security. For these reasons, enabling DoH is a great choice if you’re concerned about the security of your connections.

However, the benefits of encrypted DNS don’t outweigh the drawbacks. While DoH has higher performance when it comes to the user’s computer, it is still susceptible to certain types of analysis. In particular, hackers can trace encrypted DNS traffic, but they’d have to decrypt the domain name to determine the source. For this reason, the security benefit of encrypted DNS may not outweigh the costs of encrypting DNS traffic. The complexity of this process can make processes slower and more vulnerable.

While DoH is the fastest DNS available, it does suffer from the highest wait times and web page load times. The difference between DoH and other encrypted DNS protocols depends on who’s providing the DNS for your device. Typically, if you’re using a DoH VPN, you should choose a reputable provider with high performance. But if you’re not confident in their security, you can always force them to use HTTPS instead.

Although DNSCrypt is faster than standard DNS, it’s still not as fast as standard DNS. In fact, the difference between encrypted and unencrypted DNS is 2x as much. And if you’re on a public WiFi network, a VPN connection will cause your connection to slow down. The only way to test this is to use a VPN. It’s the fastest VPN, but you’ll want to look for a provider that has DNS over TLS.

While encrypted DNS is slower than plain-text DNS, it can be worth it if you’re more concerned about your privacy. While it’s not impossible to secure your connection with an SSL certificate, an encryption service may be a better choice. You can also use it to protect your identity and hide your activities online. In addition to speed, the benefits of encrypted DNS over plaintext are countless. If you’re worried about the security of your internet connection, you should opt for a server that supports the standard.

Encrypted DNS has several advantages, but it’s not as secure as plaintext. DoH protects the privacy of the user and protects them from third-party trackers. While it’s not as secure as plaintext, it’s more secure. But it’s not completely secure. Nevertheless, it’s safe to use it. If you’re worried about security, doH is a good option.

As the speed of encrypted DNS improves, it’s more secure. It is also more reliable than plaintext DNS. Despite the increased security, HTTPS and DNS are incompatible. If you’re concerned about your privacy, don’t use it. You might be exposed to malware. So don’t worry! There are several ways to make HTTPS and DNS work for you. If you’re concerned about privacy, make sure you’re using a VPN.

There are some drawbacks to HTTPS-based encrypted DNS. While it’s more secure, it also increases the amount of data that is transmitted by the DNS. DoH’s requirements require that DNS traffic be encrypted, but this is the only way to guarantee privacy. It also increases the speed of HTTPS-based services. While it may be slow, HTTPS is faster than plaintext. So what’s the real difference?

APNIC has a strong argument against DoH. They argue that encryption should be performed on the existing infrastructure. It will also increase latency. APNIC is concerned that the extra security will not be worth the speed loss. But if you want to be anonymous, doH is the way to go. Its performance advantage is a major plus. The privacy that you get with encrypted DNS is better than any other DNS.

Encrypted DNS vs. Unencrypted DNS

DNS (Domain Name System) resolution is the process by which a computer translates a website address (such as into the corresponding IP address that it needs to access the website. Traditionally, this process has been conducted in plain text, leaving it vulnerable to eavesdropping, tampering, and other forms of malicious activity.

Encrypted DNS, also known as DNS over HTTPS (DoH) or DNS over TLS (DoT), is a relatively new technology that encrypts DNS requests and responses, making them more secure and private. With encrypted DNS, DNS queries are sent through a secure channel and resolved by a DNS server that supports encryption. This makes it harder for attackers to intercept or manipulate DNS traffic, which is particularly important in the context of sensitive transactions such as online banking or email.

Compared to unencrypted DNS, encrypted DNS offers several benefits. One of the most significant advantages is enhanced security and privacy. Encrypted DNS makes it more difficult for hackers or internet service providers (ISPs) to monitor or tamper with DNS traffic. This is particularly important for users who access the internet over public Wi-Fi networks or who live in countries with high levels of internet censorship. Encrypted DNS can also help to prevent DNS hijacking, a type of cyberattack in which a user’s DNS requests are redirected to a malicious website, potentially exposing them to phishing scams, malware, or other threats.

Another benefit of encrypted DNS is its ability to bypass censorship and geolocation-based restrictions. In some countries, internet service providers are required to block access to certain websites or services. Encrypted DNS can help users to access these sites by bypassing the DNS filters imposed by their ISPs. It can also help to circumvent geolocation-based restrictions, allowing users to access content that is otherwise unavailable in their region.

Despite its benefits, encrypted DNS is not without its challenges. One concern is that it may be slower than unencrypted DNS, particularly if users connect to DNS servers that are located far away or experience high levels of traffic. This can lead to slower website loading times and an overall slower internet experience. However, recent studies have shown that the performance difference between encrypted and unencrypted DNS is minimal, and may even be faster in some cases.

Speed Comparison

The speed of DNS resolution can have a significant impact on overall internet performance, particularly for users who access the internet frequently or rely on time-sensitive applications such as online gaming or video conferencing. As such, it is important to compare the speed of encrypted and unencrypted DNS to determine whether encrypted DNS is slower.

Several factors can affect the speed of DNS resolution, including network latency, DNS server location and load, and DNS caching. Network latency refers to the time it takes for a DNS request to travel from a user’s device to a DNS server and back again. This can be affected by factors such as the distance between the user and the DNS server, the quality of the user’s internet connection, and the level of congestion on the network.

DNS server location and load can also affect the speed of DNS resolution. If a DNS server is located far away from the user or experiences high levels of traffic, it may take longer to process DNS requests, leading to slower website loading times. Similarly, DNS caching can affect the speed of DNS resolution, as cached DNS entries can speed up subsequent requests for the same website.

To compare the speed of encrypted and unencrypted DNS, researchers have conducted various tests using different tools and methods. One common approach is to measure the time it takes for a website to load using different DNS resolution methods. Another approach is to measure the time it takes for a DNS query to be resolved by different DNS servers.

Recent studies have shown that the performance difference between encrypted and unencrypted DNS is minimal, and in some cases, encrypted DNS can even be faster than unencrypted DNS. For example, a study conducted by Mozilla found that the median time to load a website using encrypted DNS was only 6 milliseconds longer than unencrypted DNS. Similarly, a study conducted by Cloudflare found that its encrypted DNS service,, was on average 20% faster than the average of other public DNS services.

However, it is important to note that the speed of DNS resolution can vary depending on a range of factors, including the user’s location, the DNS server’s location and load, and the quality of the user’s internet connection. As such, users may experience different performance results when using encrypted and unencrypted DNS.

Other Considerations

When considering the use of encrypted DNS, there are several factors to take into account beyond just its speed and security benefits. In this section, we will discuss some of these considerations.

Security and Privacy Concerns

Encrypted DNS can provide enhanced security and privacy, as it encrypts the DNS queries and responses to prevent eavesdropping and tampering. However, it’s worth noting that not all encrypted DNS providers are equal in terms of their security and privacy practices. Users should be cautious when selecting a DNS provider and should look for those that have transparent privacy policies, use strong encryption protocols, and have a good track record of protecting user data.

Encryption Standards and Protocols Used

Encrypted DNS providers use different encryption standards and protocols, which can affect their performance and security. Some popular encryption protocols used in encrypted DNS include DNS-over-HTTPS (DoH), DNS-over-TLS (DoT), and DNSCrypt. Each protocol has its own strengths and weaknesses, and users should choose a provider that uses a protocol that meets their specific needs and priorities.

Risks of Third-Party DNS Providers

Using a third-party DNS provider can expose users to certain risks, such as DNS hijacking, phishing, and malware attacks. Users should be careful when choosing a third-party DNS provider and should ensure that the provider is trustworthy and reputable. It’s also a good idea to verify the DNS provider’s IP address to ensure that it’s not associated with any malicious activity.

Potential Impact on Online Advertising and Content Delivery

Encrypted DNS can potentially impact online advertising and content delivery, as it can prevent ISPs and other entities from tracking users’ DNS queries and using that information for targeted advertising or content delivery. While this can be seen as a benefit by some users, it’s worth noting that some content providers and advertisers may respond to encrypted DNS by blocking or limiting access to their content for users who are using encrypted DNS.

Compatibility with Devices and Networks

Encrypted DNS may not be compatible with all devices and networks, particularly older or less common ones. Users should ensure that their devices and networks support encrypted DNS before switching to it.

Compatibility with VPNs and Other Privacy Tools

Encrypted DNS can be used in conjunction with VPNs and other privacy tools, but users should ensure that their DNS queries are not leaked outside of the VPN or privacy tool. Some VPNs and privacy tools have built-in encrypted DNS features, while others require users to manually configure encrypted DNS settings.

Availability of Encrypted DNS Options

Encrypted DNS is not yet widely adopted, and some ISPs and network administrators may not offer or support it. Users should check whether encrypted DNS is available and supported before switching to it.

Major Providers and Their Features

There are several major encrypted DNS providers, each with its own set of features and benefits. Some popular providers include Cloudflare, Google, Quad9, and OpenDNS. Users should compare the features and performance of different providers before choosing one that meets their specific needs and priorities.

Open-Source and Community-Driven Alternatives

In addition to commercial encrypted DNS providers, there are also open-source and community-driven alternatives, such as DNSCrypt-proxy, Stubby, and Unbound. These alternatives offer users greater control over their encrypted DNS settings and can be tailored to specific use cases. However, they may require more technical expertise to set up and configure.

Ease of Setup and Configuration

Encrypted DNS providers vary in terms of their ease of setup and configuration. Some providers offer simple and intuitive setup processes, while others may require more technical knowledge to set up and configure. Users should choose a provider that offers a setup process that is suitable for their level of technical expertise.


In conclusion, there are several factors to consider when choosing whether to use encrypted DNS or not.
