convert src to a number e.g. A.B.C.D => (A*256*256*256)+(B*256*256)+(C*256)+D and filter by equivalent numbers for your ip range

The following example uses the cidrmatch function as a filter to remove events that do not match the ip address:

| where cidrmatch("10.0.0.0/8", src)


Also you can use the below command as well if the above one is not working:

| search src>="10.0.0.0/8" src<="10.24.1.3"
Also, If this reply helps you, an upvote would be appreciated.
