Isn't this wrong? If the netmask is .224, it should be either 192.168.0.0-31 or 192.168.0.32-63. 192.168.0.16 does not make sense here. JohnStanley Writes: Follow Up to Previous Mail!! Filipe, To early in the day for all this math. Your right saying x.31 - x.63 for that particular SN, with x.63 being the broadcast addy and x.31 the network addy. Had to think about it a little, rough day. Just put an address in there for visual anatomy so the OP could get a picture off it. Good to know soemone is payin attention. _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
