I’ve browsed several questions about DNS setup for subdomains and not quite found an answer, so I’m hoping you can assist.
Our domain name (100storybuilding.org.au) is registered with one provider (NetRegistry), and our main web site is now hosted by SquareSpace (configured using a CNAME record). We need to set up a separate, simple web hosting service with another provider using a subdomain (trapdoor.100storybuilding.org.au).
I was originally advised that we could use their nameservers, and so created NS records for the subdomain with our registrar using the zone management tool available through their control panel. This didn’t work, though. Speaking to the hosting provider, I was advised to add an A name record for the subdomain pointing to a specific IP address for the new site, which I’ve also done. But throughout this process the subdomain has not resolved; I get a failure when using nslookup, as though it’s not recognised anywhere.
Currently we have both the A and NS records for the subdomain on our registrar, and I suspect we should only have one or the other; is that the case? I’m rusty with DNS and didn’t think this would be complicated, but if anyone can advise what records should be sufficient to for setting this up, I’d appreciate it.
