Net module socket.localAddress is changed in node 0.12

[Doweig]

Hello everyone,

today I'm happy to try to deploy some of my company's apps with node 0.12

I just upgraded from node v0.10.33 to v0.12.0 and noticed this issue with both:

net.createServer(function (socket) { ... });
tls.createServer(function (socket) { ... });

In node 0.10:
console.log(socket.localAddress); // "10.11.1.19"

In node 0.12
console.log(socket.localAddress); // "::ffff:10.11.1.19"

Any idea about what is this "::ffff:" ?

Find some answers here: http://stackoverflow.com/questions/5861107/when-is-the-hybrid-ip-notation-ffff192-168-1-4-appropriate

"It’s IPv4 expressed through IPv6 so that the application only needs to support one IP stack."

However, it's seems like I cannot use this as an IPv4. Any idea on how to convert?
Regexp will work but I find it a bit dirty...
