Can you please help me understand how this particular functionality works:

I have a domain: example.com, it's registered with GoDaddy. its nameservers are set to linode: ie. ns1.linode.com, ns2.linode.com But at the same time, I can setup a subdomain redirect on GoDaddy and it works. So, I can create a 301 redirect from www. -> non www.

Can you please tell me how GoDaddy can do this?
