Docs: Use RFC5737 for Provider Networking

Browse Source 
That'll make things more clear that with the provider networking
feature in DevStack, FIXED_RANGE will be a routed IPv4 subnet that gives
routed IPv4 addresses to instances without using floating IPs.

In this configuration we are defining FIXED_RANGE to be a
subnet that exists in the private RFC1918 address space - however
in a real setup FIXED_RANGE would be a public IP address range, so
that you could access your instances from the public internet.
publicly routed IPv4 subnet. In this specific instance we are using
the special TEST-NET-3 subnet defined in `RFC 5737 <http://tools.ietf.org/html/rfc5737>`_,
which is used for documentation. In your DevStack setup, FIXED_RANGE
would be a public IP address range that you or your organization has
allocated to you, so that you could access your instances from the
public internet.
The following is a snippet of the DevStack configuration on the
compute node.
