ipconflict's Issues

does it work in 3.96 version

I get the below error when the version was updated

ERROR: Could not find a version that satisfies the requirement ipconflict (from versions: none)
ERROR: No matching distribution found for ipconflict

exit code

Would it be possible to add exit codes to be able to evaluate the outcome using scripts?. Right now, conflict or not, the exit code is always 0
