bad remote IP address in HttpRequest.connectionInfo of a HTTPServer on Windows

What steps will reproduce the problem?

1. create a dart HTTPServer on Windows using ANY_IP_V6 in the 'bind'
2. upon a client connection arriving, print out the HttpRequest.connectionInfo.remoteAddress.address
3. repeat many connections from the same client

What is the expected output? What do you see instead?

expected output: the remote IP address
instead: we get strange values and the first connection has a different value

What version of the product are you using?
Dart 1.9.1 and previous versions too

On what operating system?
Windows 7 SP1 (64bit) and Windows 8.1 (64bit)

What browser (if applicable)?
N/A

Please provide any additional information below.
works fine on Linux
didn't try on MacOS
work fine if ANY_IP_V4 is used in the bind

full sample: https://gist.github.com/kgersen/40fc031bf045387a6045
run server.dart on a windows machine
run "client.dart http://server_ip:8192" on same machine or another

What value do you get? What do you expect instead?
"::1" for example is a valid IP address (localhost)
If you want to create an URL from this value it looks like
http://[::1]:33333

I got "::1" when I tried it on
Dart VM version: 1.10.0-edge.44764 (Fri Mar 27 15:45:24 2015) on "linux_x64"

"on Windows" as stated in the title and the "additional information" section.

I get long, meaningless values.
For instance, on the same machine, using its lan IP (192.168.1.42), when I launch 3 times "client.dart http://192.168.1.42:8192", I see this in the server window:
http connection from: ::2100:5300:0:0 at ::2100:5300:0:0%1076876064
http connection from: ::10e3:2e04:0:0%70181568 at ::e108:2005:0:0%70180416
http connection from: ::10e3:2e04:0:0%70181568 at ::e108:2005:0:0%70180416

if I use ANY_IP_V4 in the 'bind' then I get:

http connection from: 192.168.1.42 at 192.168.1.42
http connection from: 192.168.1.42 at 192.168.1.42
http connection from: 192.168.1.42 at 192.168.1.42

which is the expected behavior.

If I use client.dart on a remote machine (or "wget http://ip_of_server:8192" if Dart is not available on the remote machine) I get the same issue (so it's not a "same machine" to "same machine" issue).
