Does anybody have any example on how the Network Address value on the
NCP server object looks when it has an IPv6 address?

According to the docs
the attribute has support for NT_TCP6 and NT_UDP6 address types.

I'm asking since I'm writing some Java code that decodes the content of
that attribute into a readable string when fetching it over LDAP.
So far I have examples of IPX, TCP, UDP and URL address types.
