Hi Sasson,
When you mention a global address, do you mean
a multicast address? For example, my host machine
running windows2k looks like this ...

C:\>ipv6 if

Interface 2 (site 1): Local Area Connection
 uses Neighbor Discovery
 link-level address: 00-50-04-b6-21-5a
   preferred address fe80::250:4ff:feb6:215a, infinite/infinite
   multicast address ff02::1, 1 refs, not reportable
   multicast address ff02::1:ffb6:215a, 1 refs, last reporter
 link MTU 1500 (true link MTU 1500)
 current hop limit 128
 reachable time 39000ms (base 30000ms)
 retransmission interval 1000ms
 DAD transmits 1
Interface 1 (site 0): Loopback Pseudo-Interface
 does not use Neighbor Discovery
 link-level address:
   preferred address ::1, infinite/infinite
 link MTU 1500 (true link MTU 1500)
 current hop limit 1
 reachable time 0ms (base 0ms)
 retransmission interval 0ms
 DAD transmits 0

Should I be using the v6 address with the ff02:: prefix?
I am able to ping the fe80: : link local address from my
Linux machine just fine.

Hi Mark, fe80:: is a Link Local address. You have to supply a scope while
using such an address. I suggest you first try to use
a global address and see how this is working...

Subject: Windows IPv6 Support for Java


Folks,
I am doing some prototyping work with IPv6 on Windows2K.
I am using the Sun 1.4 Standard Edition of Java (J2SE). When
I run a simple server and try to create a socket with an IPv6
address I get the following error :

C:\java>java IPv6Server fe80::250:4ff:feb6:215a 1005
IPv6 Address: /fe80:0:0:0:250:4ff:feb6:215a
java.net.SocketException Protocol family not supported

I was doing some reading on this subject and came across
a URL that exclaimed that Windows IPv6 support for
J2SE 1.4 is not supported by Sun.

Is this true? Has any one else encountered this?
Is there a work around ...?

Thanks,
MarkL
