In some cases, users may want to use the "DOCUMENTION" address as the
internal address of NAT66.
Shouldn't a check be added here to allow the configuration of document
address?
If ULA is used, systems such as Windows and Android will not prioritize
IPv6, so some users use addresses intended for documentation purposes to
bypass this restriction.
