Thanks guys... list comprehension it is!

Either I'm crazy and I'm missing the obvious here or there is something wrong with this code. Element 5 of this list says it doesn't contain the string 255, when that's *ALL* it contains... why would it think that???

You're gong crazy:
ips = ['255.255.255.255', '128.173.120.79', '198.82.247.98',
... '127.0.0.1', '255.0.0.0', '255', '128.173.255.34']
for ip in ips:
... if '255' in ip: print ip ... 255.255.255.255 255.0.0.0 255 128.173.255.34
The problem is that you're operating in-place on an array while it's being iterated over. Since the iterator is only created once, you're can't change the array while you're iterating over it. Instead, try a list comprehension:
ips = [ip for ip in ips if '255' not in ip] ips
['128.173.120.79', '198.82.247.98', '127.0.0.1']
