You can override the global NTP settings when you create a new NTP service instance or edit an exiting one.

For information about how to set up global NTP settings, see *[Configuring Global NTP Settings](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneInfrastructure/pages/270664516)*.

> ⚠️ - The NTP service supports only IPv4 networks.
> ⚠️ - The NTP service is not supported on the following deployment types of NIOS-X servers: NIOS/CNIOS and bare-metal.

To override global NTP settings on a service instance:

1. On the Infoblox Portal, click **Manage **> **Infrastructure** > **Services**.
2. See the following topic and following the instructions if you are creating a new NTP service:
  - *[Configuring External NTP Servers](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneInfrastructure/pages/117670550)*
3. See the following if you are editing an exiting NTP service:
  1. Choose an NTP service instance on which you want to override the global NTP setting.
  2. Follow the instructions in *[Configuring External NTP Servers](https://infoblox-docs.atlassian.net/wiki/spaces/BloxOneInfrastructure/pages/117670550)*.

> ⚠️ In the **External NTP Servers** step of the wizard, use the **Override** switch to enable override. Global NTP settings are inherited by default.
