Tx, but... Why? The manpage doesn't say anything like that. To wit:

SYNOPSIS
     ifconfig interface address_family [address [dest_address]] [parameters]

     dest_address
             Specify the address of the correspondent on the other end of a
             point to point link.

     The following parameters may be set with ifconfig:

     alias   Establish an additional network address for this interface.  This
             is sometimes useful when changing network numbers, and one wishes
             to accept packets addressed to the old interface.

     netmask mask
             (Inet only) Specify how much of the address to reserve for subdi-
             viding networks into sub-networks.  The mask includes the network
             ...

Also, it works as advertised. It's only the ARP messages I could do without.
Well, that and a working static route through the aliassed IP <g>.

Furthermore, if I take the destination address out it does not work. At
least I do remember being forced to muck about till it worked.

If anything I believe I should add yet another parameter as in:

     -arp    Disable the use of the Address Resolution Protocol.

However, since this is mostly uncharted territory for me I thought I'd
better ask first <g>.
