Manage a Delegation
This section is for administrators of top-level domains only. If you have a regular domain registration, you should contact the domain registrar or registry from which you obtained the registration. You can not modify a regular domain using a root zone change.
Online System
We provide an online system that allows you to review the particulars of your top-level domain, and request changes through a web-based interface. You can also review the status of ongoing and historic requests lodged through the system.
Root Zone Management Login
Email template
While the online system is recommended, if you prefer you may also complete a text-based template and submit a change request via email. This method should be used by those requesting a change that do not have a username and password to access the online system.
