IPv6 Netmask Problems

[GoogleCodeExporter]

These should return the same mask. The latter is correct.

In [5]: ipaddr.IPv6Network('2607:f850:1::/48').netmask
Out[5]: IPv6Address('ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff')

In [6]: ipaddr.IPv6Network('2607:f850:1:0::/48').netmask
Out[6]: IPv6Address('ffff:ffff:ffff::')

This also breaks 'subnet in supernet' functionality, which is how I originally 
stumbled upon this bug.

I'm at SVN revision 232 on python 2.6.5 on 64-bit Ubuntu Lucid.

I'm not seeing this on python2.6 on a mac

Python 2.6.1 (r261:67515, Jun 24 2010, 21:47:49) 
[GCC 4.2.1 (Apple Inc. build 5646)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import ipaddr
>>> ipaddr.IPv6Network('2607:f850:1::/48').netmask
IPv6Address('ffff:ffff:ffff::')
>>> ipaddr.IPv6Network('2607:f850:1:0::/48').netmask
IPv6Address('ffff:ffff:ffff::')

Can you check to see if this is fixed for you at r236 as well?
