Abstract: The present invention relates to an injection mold device having a shear flow making part. The device comprises an injection mold provided with a cavity in which molten resin mixed with predetermined pigments is filled, a shearing force making part installed in the injection mold, some portion thereof being exposed to the cavity to be in contact with the molten resin injected into the cavity and driven by external power to cause the molten resin in contact with the surface thereof to generate shear flow by a viscosity thereby adjusting locations of the pigments within the molten resin; and a driving part for driving the shearing force making part.

Abstract: A method of advertising an address of a domain name service (DNS) server present, for example, on an IPv6 network by searching a location of the DNS server on a router network subnet using a dynamic routing protocol, storing link state information of the router indicating the DNS server existence in the router subnet, in a link state advertisement of the router, and delivering the link state advertisement to all routers within an autonomous system, to which the router belongs. When the router having the location of the DNS server is requested by another router to provide the DNS server address, the router replies to the requesting router, and the requesting router receiving the reply, advertises a router advertisement message containing the DNS server address to a subnet to which the requesting router belongs. Accordingly, a network can be set without manually setting DNS server addresses at hosts.
