Adding subdomain, pointing to different server (not Netlify), how?

Hi! I’m happily using Netlify, and I’m on the Netlify DNS (i think) with the custom domain option (www.blacktoad.pub).

But, I’m hosting a database on a different server (88.119.171.174), and I’ve installed a REST api on that, accessible via HTTP. (To be exact, PostgreSQL+PostgREST). I now need to add SSL, and in order to do so, I need a hostname.

Thus, I’d like to have a subdomain, api.blacktoad.pub point to that server. But I’m getting so confused by all the DNS options. Do I have to set this up at Netlify? Or perhaps at Porkbun, where I got my domain?

Any help is greatly appreciated!
