The -i is misplaced in this example. You'd want to use it after xargs
instead of after grep for it to do what you want. (Though you might
also want to use -i with grep to have it search case-insensitively.)
The xargs manpage states that the -i option is deprecated and you
should use -I{} instead. The {} is a string, you can use what you
wish as the string to the -I option, so a more readable example might
be:
... | xargs -Iip grep ip blacklist
