Let’s say I want to move one of my websites here, on Digital Ocean, excepting one subdomain which for now will stay at the current hosting provider (on a shared hosting plan, no dedicated IP). So:

• http://mysite.com should point to a DO droplet

• http://subdomain.mysite.com should point to the other hosting provider

Since the main domain will be configured here, how will I set up the subdomain?

Thanks!
