Root Zone Management

We are responsible for management of the DNS root zone. This role means assigning the operators of top-level domains, such as .uk and .com, and maintaining their technical and administrative details.


The Root Zone Database contains the authoritative record of the operators of various top-level domains.


TLD operators can change their delegation details by submitting revised details using our online interface, or via the email template.
