IPv6 allows you to use the UDP and TCP communication functions.
(1) Overview of definition information files
The following shows the definition files that must be configured before you can use the IPv6 functions. For detailed
contents, see the online manual in the development environment.

(2) Allocating IPv6 addresses
1. In the network definition information file, specify basic information for using IPv6 and the definition of IPv4.
network:

ethY:
(A)
Specify the service that runs at the back end.
(B)
Specify the type of LAN to be configured.

Specify the IP address of the default gateway (router). This setting is optional.
(F)

Specify whether to enable DHCP. This definition is unnecessary if you specify a fixed IP.
