	Hello,

I've just added an IPv6 alias address to the one and only network interface
on my server like this:

	ifconfig wm0 inet6 ab:cd:ef:89::2 alias 

But "ifconfig" displays it as a second IPv6 address:

	tron@colwyn:~>ifconfig wm0
	wm0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
[...]
        	inet6 ab:cd:ef:89::1 prefixlen 64
	        inet6 ab:cd:ef:89::2 prefixlen 64

And the network stack actually treats it like a normal IPv6 addresses and
uses it for outgoing connections which is not what I wanted.

Is there any way to prevent this?

	Kind regards
