Sharing hosting and dedicated for the same domain

Hello,

I have a website www.mywebsite.com that I hosted on my dedicated server, with the DNS on 1and1 company ( because my dedicated server with them ), now I’m testing something, I want to buy a sharing hosting with GoDaddy for the subdomain of the same site ( ex : en.mywebsite.com ), so what I have with DNS ? should I add the DNS of 1and1 and godaddy together ? knowing that my domain is registered and managed by network solutions.

Thanks in advance for your help and your advices.

Where you have your DNS (1and1) you should add an A record to point to the IP of the Godaddy server.
The host of the record is the subdomain.
