You may want to do a transition from the IP filter to IP capture. Once the IP is captured along with other variables, you can set a Virtual Report Suite to continue working with the data set excluding the IP addresses you previously filtered.
Having IP as a dimension you can build a segment to get the report you are looking for.
Note that IP may belong to PII depending on where your company operates. I would advise to contact your Legal team first if you decide to try to store IP in Adobe Analytics.
