As decided by FESCo on 2012-12-05 meeting, all proposed Features are required
to pass through the community review by announcing them on devel-announce list.
FESCo votes on new features no sooner than a week from the announcement.

* Detailed description
Fedora supports dualstack global networking. That means the computer with
Fedora is connected to internet using both IPv4 and IPv6 protocols. But many 
important system services and applications either don't do IPv6, do it 
incorrectly, or don't cope with various network conditions.

Unfortunately, while trying to improve IPv6 support, some IPv4 use cases became 
broken as well. That's why the goal of this feature is not only to support IPv4,
but to support all possible real-world cases.

Dualstack-ready software must cope with all possible scenarios including 
IPv4-only connectivity, IPv6-only connectivity and dual connectivity. 
The software must also cope with node-local (aka localhost) networking, which 
as been used by software for decades.

Though it would be nice to have all applications in Fedora fixed to work in 
any of the scenarios, it is not feasible to test that. Therefore this feature
is about major software used in servers, desktops and laptops. The list of such
applications will be completed over the time.

Bugs related to dualstack networking should be added to the following tracker
