Well, I reconfigured MacTCP to include DNS info (no easy task, mind
you: the MacTCP that comes with A/UX doesn't seem to want to leave
protected mode, even if you're root. I moved a MacOS configuration
over). After this, NCSA Telnet does DNS lookups just fine, without
ever playing with config.tel files or anything else. This is the
same experience as under MacOS --- with MacTCP's DNS info unset,
NCSA Telnet won't do DNS lookups, but with MacTCP set up Telnet will
do the lookups.

In any case, I now have NCSA Telnet 2.3 running under A/UX 2.0b9
and doing DNS lookups, so it definitely works fine.
