#+BEGIN_SRC python

import re

p = re.compile("\
[1-9]?[0-9]?[0-9]\.[0-9]?[0-9]?[0-9]\.[0-9]?[0-9]?[0-9]\.[0-9]?[0-9]?[0-9]")

FPATH = "auth.log" # you can edit here

f = open(FPATH, "r")
data = f.read()

f.close()

result = p.findall(data) # <class 'list'>

if __name__ == "__main__":
    print(result)
    print(len(result))
#+END_SRC

It is python3 script, thanks!

Sincerely, Byung-Hee
