It may not be totally clear from the documentation, but with a bit of
thinking it can be seen that -F and -w quite certainly can't work
together.  -w applies to regexps, whereas -F says that the pattern
isn't a regexp at all, because the program effectively isn't "grep",
then --- it's "fgrep".

I think what you really should be using is

        grep -w '10\.1\.3\.3' < abc
