      As observed in https://pyroscope.acs-prod-dp-02.acs.rhcloud.com/?query=process_cpu%3Asamples%3Acount%3Acpu%3Ananoseconds%7Bservice_name%3D%22sensor-59564f584-mk4cd%22%7D
      We spend a lot of CPU time checking if IP is public

      Also cluster entities use a lot of memory https://pyroscope.acs-prod-dp-02.acs.rhcloud.com/?query=memory%3Aalloc_space%3Abytes%3Aspace%3Abytes%7Bservice_name%3D%22sensor-59564f584-mk4cd%22%7D

      We should investigate this. For checking is IP is public we can consider bit operations and simd (will be in beta in Go 1.26) but maybe we can limit number of times we call it.
