True but the alias option in BSD only allows for assigning another IP address to an existing interface. Taking a second look at this request it appears to be more of a subinterface phenomenon and not an alias at all. 

As far as I recall FreeBSD does not support this sort of subinterface naming. But I wonder if there's a way to create pseudo interfaces to pull something similar off, however wonder what's the point.
