To change the nameservers for your domain, you will need to do the following:
1.Sign in to your Namecheap account.
2.Select Domain List from the left sidebar and click the Manage button next to your domain:
3.Find the Nameservers section and select your preferred option from the drop-down menu.
4.You should choose from four possible options:
CustomDNS – Add the Nameservers Provided by us
5.Click on the green checkmark to save the changes:
Nameservers changes do not propagate instantly. Once your nameservers are changed, it may take up to 24 hours (more, in rare cases) for local ISPs to update their DNS caches so that everyone can see your website.
You can always check your domain name using any Proxy server as Proxy servers do not store cache, thus you can see the non-cached information.
That's it!
