Is it possible to use LE and issue certificates for public IP without domain names ?

It is possible to purchase certificates for IP addresses, but not from Let’s Encrypt. Let’s Encrypt may offer IP address certificates in the future, but as of September 2018 we do not.

What is the greater picture here?

No, no certificates will be issued for IPs, only for DNS names.

Well I saw some hosters or cas give certs for IPs, so it must be possible, but as i said LE won’t do that.

I think the current Baseline Requirements norm is not to issue certificates for private (RFC 1918-reserved) IP addresses, while certificates for public IP addresses are still permitted. However, Let’s Encrypt has decided not to issue certificates for bare IP addresses even if this would be permitted…

Thanks for all your replies. I’m working on an application for an organisation, they have an external IP address to allow external access on the web server but no domain names and I wanted to use https.

By using and restricting useable SSL to the Domain Name System it makes free and secure communication subject to identification of nam…

If I recall correctly, the standard forbids SSL certificates assigned directly to IP addresses.
