Restoring an old site

Hi all,

I had a wordpress site that I saved from backup that was shut down 5 years ago. I now have access to unlimited web hosting, so I thought I’d poke around again. I uploaded the database, changed wp-config and gave it a dedicated IP. The trouble is, I don’t own the original domain name anymore. Everytime I navigate to the IP I’ve given the site, it instantly redirects to myolddomain.com and can’t find the site. Is there something I can do to make this navigable by IP only?
