I have problem with the netaddr package - version 0.7.5. This code works as expected and prints out the list of ip addresses in the range:
from netaddr import IPNetwork
ipnetwork = '192.168.0.0/24'
print list(IPNetwork(ipnetwork).iter_hosts())
However, if I change the network to, say, '192.168.0.0/8' my script just hangs:
from netaddr import IPNetwork
ipnetwork = '192.168.0.0/8'
print list(IPNetwork(ipnetwork).iter_hosts())
Am I missing something or is this a bug?
EDIT
Looks like I was missing something by not realising how big that range is!

Are you sure that it's not just taking a lot of time? You are making a list out of the iterator. When I run that on my machine, I get 100% CPU usage and memory usage increase. I can also print out the entire range if I use the iterator directly.

Whoops, sorry I've just done that. I didn't realise the range was so big.

@normski Yup, 2**24 elements, totally nothing special =)
