This piggy backs off of Issue 17
(http://code.google.com/p/ipaddr-py/issues/detail?id=17).

I've noticed the problem actually existing in latest trunk revision as well
(revision 71).

What steps will reproduce the problem?

In [1]: from ipaddr import *

In [2]: addresses = [IP(ip) for ip in IP('::1.1.1.0/120')]

In [3]: addresses.extend([IP(ip) for ip in IP('1.1.1.0/24')])

In [4]: len(addresses)
Out[4]: 512

In [5]: addresses[0]
Out[5]: IPv6('::101:100/128')

In [6]: addresses[-1]
Out[6]: IPv4('1.1.1.255/32')

In [7]: CollapseAddrList(addresses)
Out[7]: [IPv4('1.1.1.0/24')]

What is the expected output? What do you see instead?

In [7]: CollapseAddrList(addresses)
Out[7]: [IPv4('1.1.1.0/24'), IPv6('::101:100/120')]

Or, alternatively (with a better representation of the IPv6 addresses) :-

Out[4]: [IPv4('1.1.1.0/24'), IPv6('::1.1.1.0/120')]

What version of the product are you using? On what operating system?

Windows XP

Please provide any additional information below.

Aside: Is this the right place to be raising these bugs or should we be
raising them against the Python bug tracker now that this project has been
integrated in the the Python 2.7 and 3.1 trees?

Thanks,

Dave M.
