1791 TCP And UDP Over IPX Networks With Fixed Path MTU. T. Sung.
April 1995. (Format: TXT=22347 bytes) (Status: EXPERIMENTAL)

1792 TCP/IPX Connection Mib Specification. T. Sung. April 1995.
(Format: TXT=16389 bytes) (Status: EXPERIMENTAL)

Notice the 'Status:' tag, and then look at RFC2026 section 4.2.1

4.2.1 Experimental

The "Experimental" designation typically denotes a specification that
is part of some research or development effort. Such a specification
is published for the general information of the Internet technical
community and as an archival record of the work, subject only to
editorial considerations and to verification that there has been
adequate coordination with the standards process (see below). An
Experimental specification may be the output of an organized Internet
research effort (e.g., a Research Group of the IRTF), an IETF Working
Group, or it may be an individual contribution.

Tae Sung was working for Novell in San Jose, CA (.us) and this seems
to have been a dead end - recall that Novell NetWare was an major
networking O/S, but it was pretty well locked to IPX. I know you
could get it to acknowledge the existence of IP and if you loaded the
right NLMs on the server, you could get it to _route_ IP (and Appletalk
Phase I), but I think it was some time later (after NetWare 4.1) before
they bit the bullet and actually started _running_ IP (and even when
they did, the basic directory services remained IPX).

Old guy

Do you mean un numbered ip?
0.0.0.0?

I would assume he meant "using some other protocol completely".
