Benefits of using .hk LOCK:

.hk LOCK will “lock” your domain names against any changes of name server information. The prohibition is at the “registry side”, that is, at HKIRC’s system. Your registrar of .hk / .香港 domain names will appoint authorised persons, who can request an “unlocking” of the modification functions at HKIRC when necessary. HKIRC will only unlock the domain names for a short interval after a thorough and rigorous offline verification process with the authorised persons. These measures, and the underlining security policy framework, will ensure your .hk / .香港 domain names are protected with the highest security standard of the industry.
