I believe you are referring to a Custom Web Report rather than creating a single Web Reports property.
If these values are already available as separate Retrieved Properties (RPs) in your environment, I would recommend displaying each property in a separate column rather than combining all network details into a single column. This makes the report easier to read, filter, and work with.
If you already have the required RPs created, you can use a Custom Web Report similar to the example below to populate the desired network information.
