I don't think this will help that much. As belltaco says, you can get a (paid) SSL Certificate for IPs. However there are caveats - it can't be a private IP.

As belltaco says, you can get a (paid) SSL Certificate for IPs.
However there are caveats - it can't be a private IP.
All the paid certificate providers won't issue certs for RFC1918 or other non-publicly routable IP ranges.
So, you'd need to have a public IP, and be able to prove control of it in some way.
If your use-case is TLS Certs on your home/lab/internal networks -- this isn't going to help.
e: To be clear, LetsEncrypt would likely issue for this domain, however they won't be able to verify ownership using the TLS-SNI-01 or TLS-ALPN-01 methods by directly calling 192-168-1-1.backname.io, and you can't meet the DNS-01 challenge requirements because this service doesn't let you set DNS records.
