I want to generate certificates for embedded devices that do not have a domain name. Can I get a certificate issued for an IP address and not a domain name?
This is a general need for embedded devices. Currently self-signed certs are used for many embedded devices, but it would be much better to enable the device to use the let’s encrypt client and generate a real cert locally. However, the device will not have a domain name – as it is always connected to by explicit IP address.
Is this possible?
We would like to integrate the client into our embedded platform and offer this to device builders.
