What you are looking for here is to create a Quality Profile which does not include this specific rule. I let you follow the documentation to know how to proceed.
Please also note that these are not False Positive per se. By definition Security Hotspots are not proven vulnerabilities, but a sensitive part that needs to be reviewed. Read more about it in our documentation about Security Hotspots.
So a better approach would be to review them, make sure the usage of an hardcoded IP is fine is this context, and mark the Hotspot as reviewed.
Sorry to hear that RSPEC-1313 doesn’t provide interesting results in your case.
In order to try to improve this rule for all users, can you tell us why you consider the issues you got are false positives? it is not IP addresses that are highlighted? the IP addresses are not “sensitive”?
