The line '10.0.23.4' in exclude_list.txt matches the line '10.0.23.48' in start_list.text. That is, the first line is a substring of the second line. So this usage of 'grep' doesn't do what you want.
To get the effect you want, also use the -x option. E.g.: grep -vxF -f exclude_list.txt start_list.txt
