Add a subdomain to direct to a test domain
I restored a backup of linode y.y.y.y to a new linode with IP x.x.x.x. Currently my domain records point to y.y.y.y
I would like to test this backup and I thought I could add a new A/AAAA record in mydomain.com with domain test and ip x.x.x.x. I then expected that the url http://test.mydomain.com would direct to ip x.x.x.x. What actually happens is that http://test.mydomain.com redirects to http://mydomain.com at IP y.y.y.y.
I also have an A/AAAA record for *.mydomain.com which points to IP y.y.y.y. Could this be the issue? My web server is setup to handle different apps such as app1.mydomain.com and app2.mydomain.com, which I think is why I added this record. I believe I could change the *.mydomain.com to a specific myapp1.mydomain.com if needed (I only have 1 app currently).

Without knowing the specific domain, I'm going on a hunch here - did you set up a wildcard DNS record for your website? Wildcard DNS records work to redirect any subdomain not recognized back to the regular domain. Like, https://randomword.mydomain.com would redirect to https://mydomain.com unless there's an A record for https://randomword.mydomain.com that would point to a specific IP address.
There's also DNS propagation, which can be affected by the TTL on a domain that already exists. I usually use DNSChecker.org while working with DNS issues. It checks from servers around the world to test where different locations see whatever changes are being made.
