When creating a new BMC interface on existing host,
I set Name : proxy2-ipmi
Domain: example.com
Subnet : dc1

It seems that foreman try to set DNS A record without domain.
See following traces.
If I set in Name field a valid FQDN saving works.

Foreman and smart-proxy 1.2.0

I get an error on Foreman side :
