  • What's the best way to split a domain between Opalstack and another provider?

I have a domain where I want most subdomains to be hosted on Opalstack, but one particular subdomain is hosted on a VPS operated by another provider. I don't fully understand nameservers and DNS but right now my nameservers for the domain are set to Opalstack, and I'm not sure how I would redirect one specific subdomain over to an external IP address. Is this possible, perhaps by adding an 'A' record? Or do I need to use my registrar's nameservers for that domain and do it there?

    kylotan Since your domain is using our NS, you can use our DNS service to point individual subdomains to external hosts.

    If you want to point a subdomain at an external IP, then an A record is what you need.

    To do so:

    1. Add the subdomain via https://my.opalstack.com/domains/.
    2. Add a DNS record via https://my.opalstack.com/dns/ with:
      • Domain: your new subdomain
      • Type: A
      • Content: your external IP address
      • Everything else: keep the default values

    The A record should go live within a few minutes, but it could (rarely) take an hour or more to fully propagate.
