I'm trying to redirect a sub-domain off my main domain
r.example.com to another server. From what I've found so far, I can do this by simply adding a new line to the DNS file, like so:
r 14400 IN A 18.104.22.168
but that doesn't make much sense to me (I would think you'd have to specify name servers somehow).
How would I go about properly sending this single sub-domain to another server so that the user on the other end can adequately grab it and use it for their website? I know the three name servers for where I want to point it too, but can't find how to do this. Is it even possible to treat a sub-domain as basically another domain with a DNS configuration, or would I possibly need to do this higher up with my domain provider?
