Why Turn Off DNS over HTTPS?

DNS over HTTPS (DoH) is a protocol that encrypts Domain Name System (DNS) requests using the HTTPS protocol. This provides several advantages over traditional DNS, including:

• Increased security: DoH prevents attackers from eavesdropping on DNS requests and manipulating them in a Man-in-the-Middle attack. This makes it more difficult for attackers to track your online activity or redirect you to malicious websites.
• Improved privacy: DoH hides the domains that you are accessing from your ISP and other network providers. This can help to protect your privacy and prevent your ISP from tracking your online activity.

However, there are also some potential drawbacks to using DoH. These include:

• Performance: DoH can slightly slower than traditional DNS, as it requires an additional HTTPS connection to be established.
• Compatibility: DoH is not supported by all operating systems and browsers. This means that you may not be able to use DoH if you are using an older device or browser.
• Security concerns: Some experts have raised concerns about the security of DoH. They argue that it could make it easier for attackers to launch denial-of-service attacks and that it could be used to censor the internet.

Ultimately, the decision of whether or not to use DoH is a personal one. If you are concerned about privacy and security, then DoH is a good option. However, if you are concerned about performance or compatibility, then you may want to stick with traditional DNS.
