I currently have a domain with Winhost but have an entire site and database setup on my 1&1 server. Without transferring away from Winhost I want to point the domain to 1&1's NS. I looked through the Winhost DNS Options and don't see where I should put the NS1 and NS2 details from 1&1 to point to their host. I did change the IP address to my 1&1 server, which appeared to be the only option. Is this enough?
