You know, unless you have an ulterior reason for merging all the files, you
could probably just read each of them with a loop in python. Or use python
to build the main file - which would eliminate your need for that error
check.
Assuming that the first element in the line will always be the IP, this
should help:
In [12]: myline = '192.168.1.1 Gnutella File Search 24 5/15/2009 0:48'
In [15]: ip = myline.split(' ')[0]
In [16]: split_ip = ip.split('.')
In [17]: split_ip
Out[17]: ['192', '168', '1', '1']
