The domain registrar has closed. What to do?

Question

Domain name market

I own several domains that were bought over 10 years ago from domainorb.com (don't ask me why - I didn't buy them).
Now the hoster, as I understand it, has closed (their domain is for sale, support does not work).
How can I regain access to domains? I want to change dns-records, but there is no access.

Answer 1

Find out who their top registrar is and try contacting their support.
