   while [ -z "$REPLY" ]
   do
      printf "$1"
      read     
      if ! echo "$REPLY" | grep -qE "^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.|$)){3}$"
      then
         echo "Illegal input"
         REPLY=""
      fi
    done
    [ $# -gt 1 ] && printf -v "$2" "%s" "$REPLY"
}

get_three_quad "
Enter first three quadrants of router address (must contain three periods)
Example- xx.xxx.xx. : " PT1ADD
echo "You entered: $PT1ADD"

ah! That was the missing piece to the puzzle. Thanks for your help.
