okay, now I've tried to use the CIDR notation (which I usually use anyways,
but not in this case, mainly due to historical reasons or because I never
did that on any OS before).
This now works and gives me the correct netmask of 255.255.255.240 (set
before) or /28.
However, the man page of hostname.if(5) states:
STATIC ADDRESS CONFIGURATION
The following three hostname.* formats are valid for configuring
network
interfaces with static addresses:
Regular IPv4 network setup:
inet [alias] addr netmask broadcast_addr options
dest dest_addr
So,
inet 192.168.1.1 255.255.255.0 NONE
should be equal to
inet 192.168.1.1/24 NONE
However, this was exactly NOT the case in my setup. Here, stating
255.255.255.255 on the 'netmask' value led to a /8 (or 0xff000000) address
and broadcast set to 255.255.255.255, for whatever reason.
Thanks,
Joe
