.... I am running FBSD 9.3p2:
[root@kabini1, /etc, 10:16:05am] 459 % uname -a
FreeBSD kabini1.local 9.3-RELEASE-p2 FreeBSD 9.3-RELEASE-p2 #0: Mon Sep

I am trying to reset the (my) default netmask for my default network
interface from 255.255.255 to 255.255 . I changed the settings in
rc.conf & networks & did an 'infonfig re0 down/up' & nothing has changed
:-/ ....

Do I have to do a full reboot to get this to take effect ? Please advise
& TIA ....
