My test server has multiple IPv4 and IPv6 addresses.
There is an option for caddy -host ipaddre/host to start listening on a single IP of hostname.
I tried to get this on 2 IP addresses, but that didn’t work.
Is this possible?
I don’t know if that is possible only using the command line options, but you can create a Caddyfile in the root path of your website with this content and it should work:
