ICANN developed DNSSec, a security protocol for more encrypted communication between the various servers participating in DNS lookups. It fixes security holes that would allow hackers to hijack DNS lookups by intercepting information sent between DNS root servers and other directory servers.

By spoofing a valid domain, attackers can redirect consumers to a malicious domain when they ask for a lookup of a legitimate domain. Phishing and malware uploading are two possible activities on such sites.

In order to prevent attackers from forging user-sent DNS requests, DNSSec requires that all DNS servers at every tier digitally sign their requests. This establishes a reliable line of communication, guaranteeing that the request hasn't been tampered with at any stage of the lookup process.

DNSSec can also check to see if a domain name actually exists, and if it doesn't, it stops a fake domain from being sent out to unsuspecting users.

exactly what is dns over https (doh)?

There have nevertheless been DNS-based cyberattacks that exploit deception to insert malicious code into the DNS system, despite the fact that DNSSec addresses possible weaknesses within the distributed network of DNS servers.

DNS over HTTPS, or DoH, is an Internet Engineering Task Force (IETF) standard that encrypts DNS requests in the same manner that the HTTPS protocol already protects the vast majority of web traffic. This is one of the most significant changes in DNS's lengthy history.

However, the transition to DoH is not without criticism. DoH's encryption of DNS requests has been criticized by both parents and IT departments for potentially preventing them from installing parental controls over their children's internet use.

DNS over HTTPS adoption has lagged behind. Users are pre-installed with the most recent versions of Chrome and Firefox, however they are free to disable DoH if they like. Organizations who wish to exert some control over their employees' choice of web browsers and browser versions can easily do so by turning it off. However, many of the most prominent ISPS have not yet enabled DoH on their end.

discovering my dns server

When you connect to the internet, your internet service provider (ISP) will often set up the DNS server that you will use automatically. Browserleaks.com is only one of many online tools that can tell you details about your current network connection, including the IP addresses of your principal name servers.

Your Internet service provider (ISP) probably has a default DNS server set up, but you're not obligated to use it. If, for example, the ISP utilizes its DNS servers to divert queries for nonexistent addresses to pages containing advertising, consumers may have motivation to avoid using the ISP's DNS.

Alternatively, you can use a public DNS server to perform the role of a recursive resolver on your computer. Google's DNS service is quite popular and widely used. Internet Protocol address
