While testing the tool I found a place where we indeed can have IP addresses in folder names. Below is already a cleaned version that shows that the filename is correctly cleaned, the directory gives away the IP though:

must-gather.aws.cleaned/quay-io-openshift-release-dev-ocp-v4-0-art-dev-sha256-eede85cbd33388f7e18954e5ce8ad9616e91df05ace604966c0a44111d85c897/namespaces/openshift-kube-apiserver/pods/installer-4-ip-10-0-187-218.ec2.internal/installer-4-ip-x-ipv4-000001-x.ec2.internal.yaml

AC:

• folder names must also be included in the obfuscation logic
• unit testing
• including the above case for the IP obfuscator as a regression test
