At his point I think it would be good to explain what you are really trying to 
do, rather than how you would like to do it. What do you expect to see if you do 
what you want, and what tools would you use in place of the normal tools which 
expect an alias?

Note, adding a address via "ip" works in some odd ways you might not expect, and 
you have to set up routing by hand as well. What is wrong with the alias method 
which works for the rest of us?
