You don't need eval, 1 parse is enough.
Code:
#!/usr/bin/ksh
#simple script to grep for the IP of the host in any file
echo -n "Enter the IP address you want to find:"
read IP
log=/tmp/ipfind.out.$IP
echo "greping all files for $IP"
echo "This will take a considerable amount of time to complete..."
echo "Scripts logs to /tmp/ipfind.out.$IP"
# IP include ., which is special char for regexp, so you need change . -> \.
IP="${IP//./\\.}" 
# find regular files and grep IP, take time, output only filenames which include $IP
find / -type f -exec grep -l "$IP" {} \;  > $log  2>/dev/null
echo "Script complete. please check $log"
