Need some help here

Hi, I will try to brief as I know some of you will probably see what im trying to do..

What I am trying to do is have the IP address of the machine compare its IP to the IP that is on the server. I am trying to get it to read the first two octets (10.122.x.x). If the first two octets are different then that of the IP on the server I would like it to send a email to notify that the computers IP has been changed. The reason for this is to keep track of the computer. We have several schools and each school is distinguished by the second octet ("school 1" 10.111.x.x, "school 2" 10.122.x.x". I have the naming of the computer and the email set, I am just stuck on it comparing the first to octets.. Any help is appreciated.

Script:

#! /bin/sh

PATH=/bin:/sbin/:/usr/bin/:/usr/sbin

HWADDRESS=`ifconfig en0 | grep ether | awk '{print $2}'`
IPADDRESS=`ifconfig en0 | grep inet\ | awk '{print $2}'`
SUBNET=`echo $IPADDRESS | awk '{print $2}'`
WEBSERVER='http://10.108.1.227/computer_log/'
NAMEFILE='namelist.txt'
WEBNAMELIST=$WEBSERVER$NAMEFILE
NAMELIST=`curl -fRs -o /tmp/namelist $WEBNAMELIST`
NAMELIST_RESULTS=`grep $HWADDRESS /tmp/namelist | awk '{print $2}'`
IPLIST_RESULTS=`grep $IPADDRESS /tmp/namelist | awk '{print $2}'`
MATCH=`echo $IPLIST_RESULTS | awk '{print $2}'`

###### SET COMPUTERNAME VARIABLE TO CURRENT NAME IF NO VALUE IN NAMELIST OR VALUE IN NAMELIST ######
if [ "$NAMELIST_RESULTS" = "" ]; then
COMPUTERNAME=""
else
COMPUTERNAME=$NAMELIST_RESULTS
fi

###### IF COMPUTERNAME IS BLANK, SET NAME TO HWADDRESS, OTHERWISE SET TO NAMELIST VALUE ######
if [ "$COMPUTERNAME" = "" ]; then
NONAME=`echo $HWADDRESS | awk '{ gsub(":", ""); print $0}'`
ncutil setprop / computer-name $NONAME
ncutil -activate setprop / local-host-name $NONAME
else
ncutil setprop / computer-name $COMPUTERNAME
ncutil -activate setprop / local-host-name $COMPUTERNAME
fi

##### CHECK IP ADDRESS!, AND SEND EMAIL IF COMPUTER IS NOT IN IP RANGE #####

if [ "$SUBNET" = "$MATCH" ]; then
exit
else

sudo postfix start

echo "Computer $COMPUTERNAME has been moved!! The IP address of this machine is now $IPADDRESS" | mail -s "Computer-$COMPUTERNAME has been moved" email@email.org

fi

exit

NAME

       script-email - Amanda script to send email notifications

DESCRIPTION

       script-email is an Amanda script implementing the Script API. It should not be run by users directly. It sends a notification email to the
       addresses specified in the MAILTO property.

PROPERTIES

       This section lists the properties that control script-email's functionality. See amanda-scripts(7) for information on the Script API,
       script configuration.

       MAILTO

	   List of email addresses that will receive an email on command execution. It is a multi-valued property:
	     property "MAILTO" "amanda@domain.com" "sysadmin@domain.com" "amandauser@domain.com"

EXAMPLE

       In this example, script-email is scheduled to be run before the DLE, on the server.  The unqualified email address amanda will be passed to
       the email system unchanged.  The script is then attached to a dumptype, which can then be specified for any DLEs which require
       notification.
	define script-tool pre-email {
	  comment "email me before this DLE is backed up"
	  plugin  "script-email"
	  execute-on pre-dle-backup
	  execute-where server
	  property "mailto" "amanda"
	}

	define dumptype user-tar-email {
	  user-tar
	  script "pre-email"
	}
