Hi Rick, There's no freebsd machine I've ever had (any version) that has had the ip specified without the netmask keyword in /etc/rc.conf.
Until https://lists.freebsd.org/archives/freebsd-current/2024-June/006075.html I didn't even know it was possible to configure networking and have it work properly without a netmask. So, I'm at a loss. No harm though, it still works; it just emits the error twice. Maybe the error will go away in a later patchlevel. --
