First of all, if this is the wrong forum for this, my apologises in advance.
I need some guidance related to creating a subdomain inside an existing server with an running domain already configured. This is a rather simple task, but I could not find which exactly command to execute or file to edit to accomplish this. I am a programmer rather than an infrastructure specialist, so any guidance would be appreciated.
What I need to do is to create a subdomain DNS record to point to a hosting server outside my main bytemark's server. This external server is a Godaddy server. That way, everytime I use the subdomain I get redirected to this external hosting server.
Thank you in advance for your guidance!
