DNSSEC is beneficial to all registrants and end-users. Certain groups of registrants, however, may benefit more than others. For example, e-commerce sites or those which accept highly sensitive or personal information may wish to give DNSSEC-aware end-users the added assurance that they will reach the actual website.
Be aware that DNSSEC implementation can be rather complex. For example, technical complexities could arise should owners wish to change DNS hosting providers.
Owners should also evaluate and confirm if their DNS hosting provider is technically capable to handle the complexities of cryptographic key generation, signing and key rollover processes.
Should any of these steps be implemented improperly, it could disrupt user’s access to the website.
Such considerations may have additional effects for owners, such as potentially higher fees for a DNSSEC-enabled domain name.
