Understanding and correctly using the way “web stuff” fits together can prevent many problems of the kind “our email doesn’t work since our web-site designer updated the website” and “it took over 4 hours to do what should be a 15-minute job of setting up basic settings to get you working with Office 365”.

Registrant Email Address
If you have access to Registrant Email address, you can get a UDAI by contacting the current Registrar and requesting a UDAI. It will be emailed to the Registrant Email address.
With the UDAI, and a Registrar login, you can “pull” Domain Registrar to the one you’re logged in at. Note: usually cannot change the Registrant.
Logged in at the Domain Registrar, you can change the DNS Servers
Logged in at the DNS Server Provider, you can change everything about the website.

a name like “mycompany.nz”, “mycompany.co.nz” or “microsoft.com”
“kapiti.mycompany.co.nz” is a sub-domain of “mycompany.co.nz”. If you have control of a domain you can create, modify or delete sub-domains to your heart’s content. “testing.mycompany.co.nz” is a subdomain of “mycompany.co.nz”. BEWARE “google.fraudster.com” is a sub-domain of “fraudster.com” and has NOTHING to do with Google.

a one-use only password to allow you to change Registrar and Registrar Username/password for a Domain. Once a UDAI has been used, it won’t work again. Many UDAI’s are issued with an expiry date, once this expiry date has passed, the UDAI won’t work. Once a new UDAI is issued any old UDAI is automatically expired.
