DNS over HTTPS (DoH) for web browsers provides online security by encrypting DNS queries, traditionally transmitted in plaintext. This encryption shields queries from interception and manipulation, mitigating risks associated with unauthorized surveillance or malicious activities. With DoH, each query is encapsulated within a secure tunnel, ensuring confidentiality and integrity as users navigate the internet. This technical advancement enhances the security posture of web browsers, safeguarding sensitive online interactions from potential threats.https://fc7ua07a-0g83-62fb-9feb-7684b14gv764.doh.threatdefense.infoblox.com/dns-query. This information can be obtained on the General page of the Create New Security Policy wizard inside the Cloud Services Portal. Copy the auto-generated FQDN, or click regenerate to generate a new FQDN. Note that DoH per Policy must be enabled in order to obtain the FQDN. You can also view the information in the Privacy & Security options section of your web browser (see image 1).
