Motivation: According to the Oracle documentation: > java.net.preferIPv4Stack (default: false) > > If IPv6 is available on the operating system, the underlying native > socket will be an IPv6 socket. This allows Java applications to connect > to, and accept connections from, both IPv4 and IPv6 hosts. > > If an application has a preference to only use IPv4 sockets, then this > property can be set to true. The implication is that the application > will not be able to communicate with IPv6 hosts. which means, if DnsNameResolver returns an IPv6 address, a user (or Netty) will not be able to connect to it. Modifications: - Move the code that retrieves java.net.prefer* properties from DnsNameResolver to NetUtil - Add NetUtil.isIpV6AddressesPreferred() - Revise the API documentation of NetUtil.isIpV*Preferred() - Set the default resolveAddressTypes to IPv4 only when NetUtil.isIpv4StackPreferred() returns true Result: - Fixes #5657 |

How to build
For the detailed information about building and developing Netty, please visit the developer guide. This page only gives very basic information.
You require the following to build Netty:
- Latest stable Oracle JDK 7
- Latest stable Apache Maven
- If you are on Linux, you need additional development packages installed on your system, because you'll build the native transport.
Note that this is build-time requirement. JDK 5 (for 3.x) or 6 (for 4.0+) is enough to run your Netty-based application.
Branches to look
Development of all versions takes place in each branch whose name is identical to <majorVersion>.<minorVersion>. For example, the development of 3.9 and 4.0 resides in the branch '3.9' and the branch '4.0' respectively.
