Domain Name Security Extensions (DNSSEC) is a great way to add an extra security layer to your domains. It is an advanced DNS feature, which attaches digital signature (DS) records to the DNS information. So, that way, it can establish the authenticity of the source domain name.
The purpose of which it is designed is to protect Internet users from falsified DNS data. An example of such a case can be a misleading or malicious address rather than the actual address you wanted to visit.
Once you enable DNSSEC, the DNS lookups will have to use a digital signature to prove that the origin of the site’s DNS is accurate. It is very helpful for preventing some types of attacks. In case the digital signature does not match, the browsers will not open the site.
