You can point your domain to Namecheap by using these nameservers:
After you copied the values you only need to change nameservers at your domain’s DNS Zone.
After you specify new NS records, propagation will start which can take up to 24 hours to fully propagate.
That’s it! Now you know how to point your domain to Namecheap 😊
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.
