This only works if you are actually connected. I think he wants to find
out the local address without actually connecting.

In Linux, you can only have one IPv4 address per interface (and you have
to use alias interfaces, such as eth0:0, to assign multiple addresses
to a physical link).
For IPv6 and Linux, you are right.

I guess he wants to do the equivalent of ifconfig.
