Hi @Tanul
Thanks for reaching Microsoft Q&A
What are you looking for you need to enable inside of your AKS cluster "Diagnostics Settings" the enable to collect the "Kubernetes API Server". By having those metrics enabled/collection this will have costs, make sure to validate this before to avoid having plenty of logs.
Once activated you must around 20min to propagate the rules to start collecting logs. Then you can go the logs and run query's to check it and you are going to see the traces of the IP´s.
Hope this helps. Please "Accept as Answer" if it helped, so that it can help others in the community looking for help on similar topics.
