Ping scripting

This is my first posting here, I haven't found exactly what I'm looking for anywhere else so I'm hoping you all can help. I have a portion of script here that needs to ping two servers, then return whether they are up or down (somehow), and then echo that information. Here is what I have so far. It does echo up/down, but the information doesn't change regardless of the ping success.

Code:
SERVERUP=1
SERVERDOWN=0
ping -q -c1 192.168.1.11 > /dev/null; ping -q -c1 192.168.1.10 > /dev/null
if [ $? -eq 1 ]
then
        SERVERUP=$((SERVERUP+1))
else
        SERVERDOWN=$((SERVERDOWN+1))
fi
 echo "Servers up: $SERVERUP Servers down: $SERVERDOWN"

RDS-PING(1)						    BSD General Commands Manual 					       RDS-PING(1)

NAME
rds-ping -- test reachability of remote node over RDS SYNOPSIS
rds-ping [-c count] [-i interval] [-I local_addr] remote_addr DESCRIPTION
rds-ping is used to test whether a remote node is reachable over RDS. Its interface is designed to operate pretty much the standard ping(8) utility, even though the way it works is pretty different. rds-ping opens several RDS sockets and sends packets to port 0 on the indicated host. This is a special port number to which no socket is bound; instead, the kernel processes incoming packets and responds to them. OPTIONS
The following options are available for use on the command line: -c count Causes rds-ping to exit after sending (and receiving) the specified number of packets. -I address By default, rds-ping will pick the local source address for the RDS socket based on routing information for the destination address (i.e. if packets to the given destination would be routed through interface ib0, then it will use the IP address of ib0 as source address). Using the -I option, you can override this choice. -i timeout By default, rds-ping will wait for one second between sending packets. Use this option to specified a different interval. The timeout value is given in seconds, and can be a floating point number. Optionally, append msec or usec to specify a timeout in milliseconds or microseconds, respectively. Specifying a timeout considerably smaller than the packet round-trip time will produce unexpected results. AUTHORS
