Sorry, "it doesnt seem to work" isn't a lot to go on.

What output did you expect, and what output did you actually get?

Have you tried different options to 'comm'?  If the list contains only
numeric IP addresses, the '-i' option isn't going to do you much good,
for example.

Have you tried 'diff file1 file2'?  Do you get the output that seems
reasonable from that?
