You should go and read that man page again.
I didn't have to but I did. A line beginning "netmask" is not required".
If you don't specify a netmask it will default to something that was
correct in the 80s and is probably wrong on your network. The "netmask
line" isn't required, but if you don't have a netmask line you should
specify the netmask in the address line (using "ip/netmask" syntax).
