How to access my site which domains hasn't transferred yet?


Hi, I’m currently running a trial period but requested to transfer my domain name from my old web host to DH. As this take a few days I’m wondering how do I access my site on DH (for which I already created sub domains, installed an app etc.). Usually there’s an IP or a placeholder URL or something similar, right?

If I remember correctly from my last provider switch some years back there’s a way to access the site even though the registered domain name isn’t available yet (or isn’t transferred yet, as in my case).
