How to exclude the private ip range

[nareerat_pr]

I try to exclude the private ip range with command | search NOT ( src=10.0.0.0/8 OR src=192.168.0.0/16 OR src=172.16.0.0/12)

but I still found the private ips in my search result

[bowesmana · Accepted solution]

search command is doing simple string searching, so what you want is

| where !(cidrmatch("10.0.0.0/8", src) OR cidrmatch("192.168.0.0/16", src) OR cidrmatch("172.16.0.0/12", src))
