Adding an IP address to a certificate?

[johanneskastl]

Dear all,

I am using Lego a lot in my homelab. One of the services I need a certificate for requires the service's IP address to be included in the certificate in addition to the hostname(s).

I failed to find a hint in the lego documentation on whether this is possible and if so, how to accomplish that.

Do I just add the IP as a separate --domains parameter?

Kind Regards,
Johannes

Hello,

lego supports the RFC 8738 (issues certificates for IP addresses).

The flag --domains accepts IPs, so yes just add them.

Perfect, thanks for the fast reply.
