IBM employees are certainly not alone in having Internet addresses on
their business cards.  The ones I've seen from IBM were given out in
pursuit of research.  I did not intend to malign IBM's business card
practices by my posting.  I'd just like for them to tell people an
address which works.

As someone else has pointed out, a domain address does not mean that a host
is on the ARPANET or that mail to it will use the ARPANET at any point.
Even the temporary and soon-to-be-obsolete .ARPA domain does not refer
to the ARPANET:  it refers to a certain administrative subset of the
ARPA Internet.  The Internet includes, but is not identical to,
the ARPANET.  The domain .ARPA does not even include all of the ARPANET
(not sally.utexas.edu, for example) and it does include most of MILNET.

Consider hosts in ATT.COM or OZ.AU, for examples (both real).
