Is there a certificate for IP without binding to domains or what can be offered?

Answer 1

nobody provides a certificate for ip.

When they ask "certificate for IP" - it is immediately clear that the person does not understand why he needs a certificate at all. A certificate is a digital identity that confirms by the authority of its publisher that the object (website, server, service, person) mentioned in the certificate is in fact the one it claims to be.
You can take a wildcard certificate that will confirm all subdomains of this domain (*.zhopa.ru)
You can take a SAN certificate that lists several aliases of one domain (zhopa.ru, zadnica.ru, popa.ru)
