Description of problem:
Netstat is unable to print full ipv6 addresses. More, it's unable to print 
ipv4 on ipv6 sockets adresses (::ffff:a.b.c.d addresses). Output formatting of 
netstat is trashed.


How reproducible:
Always

Steps to Reproduce:
IPV6 is enabled.
Some ipv6 client connect on the ipv6 server.
In the same time, ipv4 client connects on processes using ipv6 sockets.

Command used: netstat -n

Actual Results:
tcp        0      0 ::ffff:10.200.200.10:22 ::ffff:10.200.200.:3155 ESTABLISHED
tcp        0    298 2001:abc:def::100:3378 3ffe:501:4819:2000:2:80 ESTABLISHED 

You see somethings lacks at the end of each foreign address.


Expected Results:
tcp        0      0 ::ffff:10.200.200.10:22 ::ffff:10.200.200.111:3155 
ESTABLISHED
tcp        0    298 2001:abc:def::100:3378 
3ffe:501:4819:2000:2000:203:47ff:fea5:3085:80 ESTABLISHED

Addresses are complete!


Additional info:
This bug renders netstat useless if ipv6 is in use.
