One of the latest innovations in this area is DNS over HTTPS (DoH), which aims to encrypt DNS traffic and provide users with more control over their online activities.
What is DNS over HTTPS (DoH)?

Bypassing Network Restrictions
- DoH can help users bypass DNS-based content blocking or censorship imposed by certain ISPs or governments.
Potential Impact of DNS over HTTPS (DoH)
The adoption of DNS over HTTPS (DoH) has the potential to revolutionize the way DNS is handled, bringing significant changes and benefits to the online experience. Some potential impacts include:
Improvement in User Privacy
By encrypting DNS traffic, DoH ensures that user queries are hidden from prying eyes, including ISPs and other network intermediaries. This shields users’ online activities and prevents unauthorized data collectionCookie Tracking: The use of cookies to track website user ac....

Standardization Efforts
DoH is still in its early stages, with different organizations and software providers implementing their own versions. Standardization efforts are critical to ensure interoperability, compatibility, and long-term stability of the protocol.
Conclusion
DNS over HTTPS (DoH) holds immense potential to enhance privacy, security, and flexibility in DNS resolution. By leveraging encryption and authentication mechanisms, DoH can mitigate many of the concerns associated with traditional DNS protocols. However, successful implementation will require careful planning, industry collaboration, and gradual adoption to address the challenges and ensure a seamless transition to a secure DNS future.
