Simply log into “Account Manager” using your username and password and select the domain name for which you wish to change DNS Servers. You will need to be prepared with the names of the No-IP DNS Servers – information provided to you when you purchased DNS services from No-IP.
Under the heading “DOMAIN NAME SYSTEM SERVERS (DNS SERVERS)” enter the DNS Servers No-IP has provided and click the “Continue” button. When the confirmation page appears, click “Continue” again and the DNS Server change will be implemented.
Note: DNS Server changes take between 24 and 72 hours (standard Internet propagation time) for the update to be completed globally.
