Stop worrying about needlessly creating lists.  Write the code in a way 
that works and is easy to understand.  If it turns out that it's not 
running fast enough, then you can go back and optimize.

BTW, for those of you into code golf:

>>> line = '192.168.1.6 > 192.168.1.7: ICMP echo request, id 100, seq 
200, length 30'

>>> dict((k,int(v)) for k,v in (s.split() for s in line.split(', ')[1:]))
{'length': 30, 'id': 100, 'seq': 200}
