> In current implementation of {{WSDiscoveryServiceImpl}}, endpoint is published with hardcoded
IPv4 multicast address:
> {code}udpEndpoint.publish("soap.udp://239.255.255.250:3702");{code}
> There is no reason to support only IPv4. Also current implementation does not support
WS-Discovery in IPv6 network when IPv4 is not available at all.
> Programatically determining network environment and switching the profile might not be
the best option (network might be temporarily at the moment of trying down etc.), so at least
I would suggest something like .. to allow to choose IPv4/IPv6 profile by system property,
with IPv4 as default. This would also allow testing IPv6 on dualstack networks.
> In {{WSDiscoveryClient}}, although address can be altered by setter or constructor, the
default one can be still switched by proposed system property.
> Multicast IPv4 and IPv6 addreses in [WS-Discovery spec, section 3.1.1|http://docs.oasis-open.org/ws-dd/discovery/1.1/os/wsdd-discovery-1.1-spec-os.html#_Toc234231817]
