[avahi] Announce Service for another Computer

[Jens Dede]

Is it possible to announce a service for another computer which name is
not resolvable via DNS or mDNS?

I like to use python with dbus.

bus = dbus.SystemBus()
server = dbus.Interface(
   bus.get_object(avahi.DBUS_NAME, avahi.DBUS_PATH_SERVER),
        avahi.DBUS_INTERFACE_SERVER)

g = dbus.Interface(
          bus.get_object(avahi.DBUS_NAME,
                         server.EntryGroupNew()),
            avahi.DBUS_INTERFACE_ENTRY_GROUP)

g.AddService(avahi.IF_UNSPEC, avahi.PROTO_INET6, dbus.UInt32(0),
            self.name, self.stype, self.domain, self.host,
            dbus.UInt16(self.port), self.text)
g.commit()

If I set self.host to an IP(v6)-Address or an unresolvable name I get an
error message. self.host = "" uses my hostname to publish the service.

How can I announce a service for any address / host?
