SX-2600CV is an external box that serves as a gateway for traditional IPv4-only devices by translating the IPv4 protocol to work over IPv6, expanding its communication range. Since devices that support IPv4 only cannot be used in an IPv6 environment, IPv4 devices would need to be replaced, incurring expenses associated with administration, configuration, and/or operation. Using SX-2600CV will make IPv4 products operable in an IPv6 environment easily and inexpensively.
