Detect and visualise IP addresses overlap

Hello. I need script/program to detect any overlap between thousands CIDRs/IPs which is distributed between multiple lists/files. Then the output must be visualized by using chord diagrams. Any additional statics or ideas will be more than welcomed. For example: $ cat [login to view URL] | head -n 3 Input number, Department, IP/CIDR 1, Systems, 1.2.3.0/24 2, Network, [login to view URL] $ cat [login to view URL] | head -n 2 Input number, Department, IP/CIDR 1, K1, 1.2.3.1 2, K2, [login to view URL] ./myscript [login to view URL] [login to view URL] We have scanned 112343 inputs, and the results can be summarized as follows: [login to view URL] has 50 input and total number Hosts/Net is 34500 [login to view URL] has 79 input and total number Hosts/Net is 423 There are 2 conflicts ———— overlap results ———— 1- conflict/overlap: (input number 1 from [login to view URL]) is overlapped with (input number 1 from [login to view URL]). 2- conflict/overlap: (input number 2 from [login to view URL]) is overlapped with (input number 1 from [login to view URL]). ————— overlap diagram ——— /home/user/[login to view URL] Note: The code must be documented and well explained. Thanks!
