You can manage your DNS records via DNS Zone Editor. To reach it, open the Domains section, and click on Manage next to the domain that you want to update:
Then, click on Change next to the Nameservers:
You'll find two options:
Use Hostinger nameservers (recommended) – use it to point your domain to Hostinger
Change nameservers – use it to specify custom nameservers and point your domain elsewhere
Finally, click on Save.
Any DNS changes need time to get updated worldwide. This process is called DNS propagation and may take up to 24 hours. During that time, a website is unreachable. Give your domain a bit of time, and it will start working soon – a couple of hours is usually enough 😊

NOTE
If your domain is pointing elsewhere by NS records, your DNS Zone management is moved to the provider you pointed the domain to and should be managed from there
