The method also can include generating, using the records, a first dataset including an inventory of IP entities that communicated with the mainframe computing system over TCP during the time period. The method additionally can include generating one or more visualizations based at least in part on information in the first dataset. The method further can include generating an allocation of the IP entities into rings representing respective potential latency sensitivities. The method additionally can include causing to be displayed outputs including the one or more visualizations and the allocation of the IP entities. Other embodiments are described. ## Claims ### Claim 1 A computer-implemented method comprising: obtaining records of TCP communications for a mainframe computing system for a time period; generating, using the records, a first dataset comprising an inventory of IP entities that communicated with the mainframe computing system over TCP during the time period;
