Welcome to the forum.

You didn't mention about the log file format. If it contains only the IP ADDRESS,
probably you can do something like,

Code:
$ cat f5
54.215.211.198
50.215.211.198
50.215.211.198
51.215.211.198
51.215.211.198
52.215.211.198
52.215.211.198
52.215.211.198
52.215.211.198
53.215.211.198
$ 
$ 
$ sort f5 | uniq -c | sort -nrk1 | head -1
   4 52.215.211.198
$


There are lots of other ways around.
