How to see website if there is no domain name yet set

Good day, how can I see website on my server if the domain in not yet bought and set my dns on it.
Can I use somehow my IP to see the domain ?
It's not a main domain but a client domain.
I just copy files to ftp and don't know how to see if the website is okey or not.

Best regards,
Janis Peksa.
